26. It is difficult to give the exact proportion of sugar to use with every kind of fruit, for some fruits require more than others. However, in general, 3/4 cupful of sugar to each cupful of juice, as shown in Fig. 5, will be sufficient. This is especially true if the season has been a dry one and the fruits are neither very sour nor very juicy.

After a wet season or with very sour or very juicy fruits, it will usually be necessary to use 1 cupful of sugar to each cupful of juice.

27. Much waste of sugar and spoiling of jelly can be avoided by the use of the test for pectin, which has just been described. After the juice and the alcohol have been mixed, pour the mixture slowly from the gla.s.s, noting how the pectin is precipitated. If it is precipitated as one lump, a cupful of sugar may be used for each cupful of juice; if in several lumps, the proportion of sugar must be reduced to approximately three-fourths the amount of juice. If the pectin is not in lumps, but is merely precipitated, the sugar should be one-half or less of the amount of the juice.

[Ill.u.s.tration: FIG. 6]

28. To a.s.sist in determining the correct proportion of sugar to use in the making of jelly, the hydrometer, or sirup gauge, which is explained in _Canning and Drying_, will be found helpful. After the juice has been extracted, mix with a small amount of it the proportion of sugar that is to be used when the jelly is cooked. Allow the sugar to dissolve completely, pour a little of the mixture into a gla.s.s or a graduate, and insert the hydrometer, as shown in Fig. 6. Regardless of the kind of juice, the hydrometer should register 25 degrees for perfect jelly. If it registers less than 25 degrees, more sugar should be added. Then if it is necessary to add either sugar or juice, the additional ingredient should be carefully measured in order that the proportions may be correct for the making of jelly. It must not be understood that a hydrometer is an actual necessity in the making of jelly, for very good jelly can be made without measuring the ingredients in this manner.

However, if a hydrometer is not used, it will be necessary to apply the best judgment possible to the rules given for the proportion of ingredients used in jelly making.

29. COMBINING THE JUICE AND SUGAR.--The mixing of the juice and the sugar may seem like a trivial matter, but in reality much is involved in combining these ingredients properly. It may be done in three different ways. In the first method, which is called _long boiling_, the sugar and the juice are mixed cold and are then allowed to come to the boiling point together. The second, which is known as _mean boiling_, consists in putting the cold juice on the stove, allowing it to boil about half the required time, and then adding the sugar, which has also been heated. In the third, which is known as the _short-boiling method_, the juice is boiled without the sugar almost the full length of time required for making the jelly, and the sugar, which has been heated, is added just before the boiling is completed.

30. Experience in the use of these three methods has shown their advantages and disadvantages. The first one, or the long-boiling process, has the disadvantage of losing sugar through the skimming that is always necessary in the making of jelly. In addition, the long boiling often causes the sugar to crystallize and thus produces a jelly that would not score very high. The short boiling is not entirely satisfactory, because of the difficulty in determining just when to add the sugar to the juice. The process of mean boiling, having neither of these drawbacks and usually resulting in jelly of excellent quality, is the most satisfactory and the one that is recommended.

[Ill.u.s.tration: FIG. 7]

To carry out this method, place the sugar in a pan in a warm oven or other place where it will gradually become heated without either melting or scorching. Put the juice over the fire in a saucepan and let it boil for 5 to 8 minutes. Then, as shown in Fig. 7, slowly add the correct proportion of hot sugar to the boiling juice, stirring constantly so that the sugar will dissolve as quickly as possible.

31. BOILING THE JUICE AND SUGAR.--The boiling of the juice, both before and after the sugar is added, should be done rapidly. During this process, it will be found that a sc.u.m will form over the top of the juice. This should be skimmed off as it forms, for it is a detriment to the jelly. As shown in Fig. 8, draw a large spoon over the top of the boiling juice from time to time and skim off the sc.u.m that rises, placing it into any small dish that is handy. It is usually advisable to do as much skimming as possible before the sugar is added, so that only a minimum amount of sugar will be lost.

The length of time required to boil the juice after the sugar is added depends very largely on the way in which the boiling is carried on. If the mixture is boiled rapidly, less time will, of course, be needed than if it is boiled slowly. Therefore, no definite time can be set for the cooking. However, several tests may be resorted to in order to determine whether the sugar and juice have boiled long enough to jell when the mixture is cold.

[Ill.u.s.tration: FIG. 8]

32. TESTING THE JELLY MIXTURE.--The testing of the mixture can be done in various ways, the one to select depending on the success the housewife has in using them. A means very often resorted to consists in dipping a spoonful or two of the mixture out of the kettle and pouring it on the flat surface of a cold dish. If it is cooked sufficiently, it will solidify when it is cold and will appear just like jelly. The disadvantage of this test lies in the fact that the jelly on the stove continues to boil while the test is being made, and as this takes several minutes, the jelly is likely to overboil to a considerable extent. Tests that can be performed more quickly are therefore more satisfactory.

33. A test that invariably proves successful consists in dipping up a spoonful of the juice and allowing it to run slowly from the spoon back into the pan. If, as shown in Fig. 9, a double row of drops forms on the spoon with the last of the jelly that remains, it may be known that the cooking is finished.

34. Another very satisfactory test is called _sheeting_. In the performing of this test, a spoonful of the jelly is dipped from the pan and then poured from the spoon into the pan again. If it is cooked to the proper consistency, large drops will form at the edge of the spoon and break off quickly.

[Ill.u.s.tration: FIG. 9]

35. FILLING THE GLa.s.sES.--As soon as it has been determined that the jelly is sufficiently cooked, it should be removed from the stove. The gla.s.ses may then be filled at once. These, together with the covers, must be thoroughly cleansed before being used, and this can be done while the jelly is cooking. After being thoroughly washed, submerge them in a pan of hot water and allow them to remain there until they are to be used. Keeping them hot in this way will prevent them from cracking when the hot jelly is poured into them. Take out one gla.s.s at a time, place it on a small plate or any small dish, and, as shown in Fig. 10, pour the hot jelly into it from the pan to within 1/4 inch of the top.

Fill the remaining gla.s.ses in the same way, and then set them somewhere out of a draft to cool. If, as the jelly cools, it seems to be a little bit thin, place it somewhere in the suns.h.i.+ne and the heat of the sun will help to thicken it.

[Ill.u.s.tration: FIG. 10]

36. CLOSING AND STORING THE JELLY GLa.s.sES.--The jelly should be allowed to cool completely and should then be closed for storing. The best results are obtained by putting a thin layer of paraffin over the top of the jelly in each gla.s.s before applying the cover. To do this, put into a small saucepan as much paraffin as you think will be needed to cover the jelly you have made and set this on the stove to melt. When it has melted, pour a layer about 1/8 inch thick over the surface of the jelly, as shown in Fig. 11. As soon as it cools, it will harden and thus form a protective covering for the jelly. When it is hard, cover the gla.s.s in the desired way. Covers of tin are perhaps the most satisfactory, but if these cannot be secured, heavy paper covers that fit into the gla.s.ses snugly will answer the purpose very well. In the event of not having covers of either of these kinds, cover the tops of the gla.s.ses with paper--any good wrapping paper will do--and then tie this paper securely. Just before putting the jelly away, label each gla.s.s with a neat label on which is written the name of the jelly. Then no difficulty will be experienced in selecting at once the kind of jelly desired when one is taking a gla.s.s from the place where it is stored.

SCORING JELLY

37. With jelly, as with canned fruit, it is a splendid idea for every housewife to score each kind she makes, so that she can determine how it measures up in its various characteristics. If it falls below the standard, this fact should be known, so that the fault can be remedied the next time. On the other hand, extreme satisfaction is felt if it is found to score high. To a.s.sist in scoring jelly, a score card is here given, and following it each one of the characteristics is discussed.

SCORE CARD FOR JELLY Per Cent.

Color 20 Solidity 25 Flavor 25 Sugar Content 25 Method of Sealing 5 --- Total 100

_Color_.-For jelly having the proper color, 20 per cent. is given. The fruit used in the making of jelly determines to a great extent the color of the finished product, but it is possible to have a very wide difference in the colors of jelly made from the same fruit. To be right, jelly should be clear, bright, and not too dark. If the juice is boiled too long, the jelly will be darker than it should be. If pulp has been allowed to pa.s.s through the jelly bag in straining out the juice, either through squeezing the bag or using a bag that is too thin, the jelly will be found to have a cloudy appearance.

_Solidity_.--When jelly is turned from the gla.s.s, it should be firm enough to stand alone. If it has not been boiled long enough, it will crush down and perhaps run like sirup. If it is boiled too long or the proportion of juice to sugar is not correct, it may be tough and leathery. Jelly whose solidity is correct scores 25 per cent. in this respect.

_Flavor_.--The characteristic flavor of the fruit used in making jelly should be retained as much as possible, and when this is the case 25 per cent. is given to the product. The flavor of the jelly is therefore dependent on the flavor of the fruit. In addition, the flavor depends on the amount of sugar used, the amount of acid in the fruit, and the length of time consumed by the boiling. Jellies boiled too long will be strong in flavor.

_Sugar Content_.--The sugar content of jelly should be determined by the amount of acid that must be sweetened. An insufficient amount of sugar will result in tough, sour jelly, while too large a quant.i.ty will make the jelly taffy-like. The correct amount of sugar, which produces the right degree of sweetness, receives a score of 25 per cent.

_Method of Sealing_.--The method of sealing may seem like a matter of little importance, but if jelly is not sealed properly, it will not be in good condition when it is to be served. To score in this respect, for which 5 per cent. is given, the jelly should be covered with paraffin and then closed with a cover or with paper in order to exclude the dust and dirt.

RECIPES FOR JELLY

38. Recipes for the kinds of jelly usually made are here given. If the directions given in the procedure for jelly making are thoroughly mastered and then applied to these recipes, the housewife will experience very little difficulty in making any of these varieties.

Other jellies may, without doubt, be made by combining the proper fruits. All that has to be done in order to determine whether a certain fruit juice or combination of fruit juices will make jelly is to apply the test for pectin already explained. Whatever quant.i.ty of jelly is desired may be made, but usually it can be handled best if not more than 6 gla.s.sfuls are made at one time.

39. CRAB-APPLE JELLY.--Crab apples are much used for jelly, as they make a product of good consistency and excellent flavor. Apples may be used in the same way as crab apples with equally good results.

Wash the apples thoroughly, remove the stems, and cut into quarters.

Make sure that the apples contain no worms. Put them into a kettle, add about half as much water as apples, and cook slowly until the apples are soft. Strain the juice through a jelly bag. Before it stops dripping, return the pulp to the kettle, add half as much water as pulp, and allow the fruit to cook again. Make a second extraction, and in the same way make a third one. Then combine the juice, and strain all of it through a bag to make it clear. Measure 6 or 8 cupfuls of juice, and pour it into a preserving kettle. Boil for about 5 minutes, straining off the sc.u.m that rises to the top. To each cupful of juice, add 3/4 to 1 cupful of sugar that has been heated. Crab apples will require 1 cupful of sugar, but apples milder in flavor will not need more than 3/4 cupful. Boil until the test shows that it has boiled long enough. Pour into hot gla.s.ses, cool, and seal. Label and then store for later use.

40. CURRANT JELLY.--If jelly having a tart flavor is desired, currant jelly should be tried. This kind of jelly is especially good to serve with the heavy course of a meal.

Wash and stem the currants. Put them into a kettle and add about one-fourth as much water as currants. Boil until the currants are reduced to a pulp. Pour into a jelly bag and strain. Make at least one more extraction, and a third extraction if there is a fairly large quant.i.ty of pulp. When all the juice has been strained from the pulp, strain it again through the bag or a heavy cloth. Measure 6 or 8 cupfuls of juice into a kettle, boil for about 5 minutes, and then add from three-fourths to an equal amount of heated sugar. Remove the sc.u.m as it forms, taking off as much as possible before the sugar is added.

Continue to boil until the tests show that the mixture has cooked sufficiently. Remove from the heat and pour into hot gla.s.ses. Cool, seal, label, and store.

41. GRAPE JELLY.--Thoroughly ripe grapes may be used for jelly, but they are not so satisfactory for this purpose as grapes that are only partly ripe. This is due to the fact that green grapes contain more pectin and, upon being cooked, produce fewer of the cream-of-tartar crystals usually found in grape jelly than do ripe ones. The procedure for grape jelly is the same as that for currant jelly. If ripe grapes are used, 3/4 cupful of sugar will be needed to each cupful of juice; but if only partly ripe grapes are used, 1 cupful of sugar will be required for every cupful of juice.

42. QUINCE JELLY.--Because of its attractive color and delicate flavor, quince jelly is much favored. The quinces may be used alone, but if a still more delicate flavor is desired, apples may be added to the quinces, or the parings and cores of the quinces may be used with apples or crab apples. To make quince jelly, proceed in the same way as for apple jelly, using 3/4 cupful of sugar to 1 cupful of juice.

43. RASPBERRY JELLY.--Either black or red raspberries may be used for jelly making. To give jelly made from these fruits a better consistency, a small quant.i.ty of green grape, crab-apple, or currant juice should be added. The procedure in this case is the same as for currant jelly.

44. STRAWBERRY JELLY.--Unripe strawberries contain a small amount of pectin, but thoroughly ripe ones are almost lacking in this respect. For this reason, strawberries cannot be used alone for making jelly. They make a delicious jelly, however, if currants are combined with them. For each 5 or 6 quarts of strawberries, 1 quart of currants will be sufficient to make a jelly of good consistency. Wash and hull the strawberries and then proceed as for currant jelly.

45. PLUM JELLY.--Plums make a jelly that many persons like. If it is desired to use plums alone, those which are not thoroughly ripe should be selected. Ripe plums do not contain enough pectin for jelly; therefore, a fruit high in pectin, such as crab apples, must be added.

The procedure for currant jelly should be followed for plum jelly.

46. PEACH JELLY.--Peaches contain so little pectin that it is almost impossible to make jelly of them unless some other fruit is added in rather large quant.i.ties. Currants, crab apples, or green grapes may be used with peaches, and whichever one is selected will be needed in the proportion of about 50 per cent.; that is, half as much additional fruit as peaches is needed. In the making of peach jelly, proceed as for currant jelly.

47. CANNING FRUIT JUICES FOR JELLY.--During the canning season, when a great deal of such work is being done, the housewife often feels that making jelly and preserves is an extravagant use of sugar. Still, fruit juices left over from canning and large quant.i.ties of fruit, such as crab apples and currants, that are not suitable for other purposes, will be wasted unless they are used for jelly. If it is not convenient to use the fruit at the time it is obtained, a good plan is to extract the juice as for jelly making and then can it. In case this is done, jelly may be made from the juice during the seasons of the year when less sugar is required for other things.

48. To can fruit juice, extract it from the fruit as for jelly making and then bring it to the boiling point. Select bottles or jars that may be tightly closed, sterilize them, fill them with the boiling juice, and seal them. Bottles may be used for this purpose if they are well corked and then dipped into melted sealing wax or paraffin. When properly sealed, fruit juices will probably keep without any further effort to preserve them, but to make positively certain that they will not spoil, it is a wise precaution to process the filled bottles or jars in boiling water for about 6 or 8 minutes in the same way in which canned fruit is processed. When treated in this way, fruit juices will keep perfectly and may be made into jelly at any time during the winter.
