Fruit may be canned with clear water, sugar syrup, or in cases, with a diluted corn syrup. In making sugar syrup, the density may vary from thin to medium or thick, according to kind of fruit to be canned, special need for economy, or individual taste. For sweet fruits — sweet berries, peaches, cherries — use thin syrup; for sour berries and other sour fruits, use medium- thick syrup; for hard fruits — pears, apples, quinces — thin to medium-thin syrup may be used. * This may be done by immersing fruit in boiling water, one or two minutes, until skins "slip easily," then dipping into cold water and removing skins.

To make it use about i cupful sugar to 5 cupfuls water. Medium-thin syrup is that which has begun to thicken and becomes sticky when cooled on the tip of a spoon; it has a density varying from 20 to 40 per cent. To make it, use about i cupful sugar to 3 cupfuls water. Medium-thick syrup is that which has thickened enough to roll up over the edge of the spoon when it is poured out; its density varies from 40 to 50 per cent. To make it, use i cupful sugar to I cupful water. ^ Only an expert in canning should attempt meats and soups. Instructions may be obtained from the United States Department of Agriculture. To insure success in all canning, observe the following: Use of sound, fresh food only. Careful preparation; quick work. The complete filling of jars or cans. Surgical cleanliness in every detail. Complete sterilization. Correct timing; an alarm-clock is helpful. Perfect sealing. 1 Farmers' Bulletin 839, United States Department of Agriculture, contains a very exact "syrup table," as well as 'detailed recipes and instructions for the canning of fruits, vegetables, meats, soups. The facts as outlined have been arranged largely from material published in this buUetin, 198 FOOD AND FREEDOM Never use artificial preservatives or canning "com- pounds" or "powders." These are unnecessary, many are harmful, and their use is forbidden or restricted in many states and by the national govern- ment. JELLY-MAKING: Principles: Jelly is made by combining strained fruit juice and sugar in certain correct proportions, de- termined by the quality of the fruit juice, and boiling this for a definite length of time. Good jelly depends upon the care and success with which this is accompHshed. "A good jelly should be bright, of good color, and clear. When removed from the glass and cut, it should retain its shape. It should sparkle, and be tender enough to quiver without breaking." There are two properties that should be present in fruit juice in order to make perfect jelly; these are pectose or pectin and acid. Pectose or pectin is the "essential jelly-making material"; acid is desirable largely for flavor. Pectose is an insoluble body present in fruits when under-ripe; as fruit ripens, pectose is converted into pectin. It is this substance which unites with the sugar, during the process of jelly -making, and solidifies or "jells" on cooling. Pectose unites with sugar more readily than pectin, therefore fruit that is slightly under-ripe makes the better jelly. Fruits with little pectin and much acid do not make good jelly.
