V. CEUESSi AND AGNES O'NEILLS INTRODUCTION According to a recent industrial census made by the National Confectioners' Association about 825,000 tons or about 13% pounds per capita of commerciall}^ prepared candy is consumed in the United States annually. In addition a large amount of home-made candy is prepared. Most of either kind contains little or no fruit. Many candies are improved by the addition of fruit and several excellent candies consisting entirely or principally of fruit can be made. The recipes in this circular are intended for use in preparing small quantities of candy for home use, or small commercial quantities with household equipment for local sale, and are not intended for use by wholesale candy manufacturers. However, the underlying principles of the various processes are the same for both large scale and home preparation, and the directions given can be modified in most cases to suit the needs of the commercial manufacturer. Retail candy makers can use many of the recipes without modification. The information presented in this circular is the result of experiments conducted in the Fruit Products Laboratory of the University of California. Healthfulness of Fruit Candij. — While most candies are wholesome, the addition of an appreciable proportion of fruit, on account of its composition, increases not only their palatability, but also their healthfulness. Fruits contain invert sugar, which is readily digested; mineral salts that tend to counteract the acidity resulting from a meat and cereal diet; fruit acids that are beneficial to health; and some fruits an important amount of vitamin C, which is of particular value to children. 1 Associate Professor of Fruit Products and Chemist in the Experiment Station. 2 Graduate Assistant in Fruit Products. CALIFORNIA AGRICULTURAL EXTENSION SERVICE [CiRC. 10 EQUIPMENT Most of the equipment required is to be found in any kitchen. In addition to the usual kitchen equipment, a candy thermometer is very desirable for most candies and necessary for some, and a syrup hydrometer is very useful in the candying of fruit. Fig. 1. — Thermometers suitable for use in small-scale candy making. Thermometer. — An ordinary Fahrenheit chemical thermometer having a solid glass stem and reading to 300° F is satisfactory. This can be purchased through a drug store from any chemical supply house for about $1.50. 1927] THE HOME PREPARATION OF FRUIT CANDY There are also available in hardware stores and in some grocery stores candy thermometers made especially for household use. Low- priced dairy thermometers reading to 300° F can be used if standard- ized in boiling water. This is done by immersing the bulb of the thermometer for about two minutes in boiling water and reading Fig. 2. — Syrup hydrometer, measuring spoons, and measuring cup. the boiling point accurately while the thermometer bulb is immersed in the actively boiling water. Water should boil at about 21.2° F, at or near sea level; in using the thermometer add to or subtract as the case requires, from the temperatures recommended in the recipes the number of degrees which the thermometer is in error. Three suitable thermometers are shown in figure 1. CALIFORNIA AGRICULTURAL EXTENSION SERVICE [CiRC. 10 Syrup Hydrometers. — Hydrometers are used in testing syrups during candying of fruits. Tliese are of many forms and are sold under several different names, such as saccharometer, sugar tester, and salometer. The Balling and Brix hydrometers indicate the percentage of sugar and are best for home use. A tall cylinder made for the purpose and shown in figure 2 or a tall jar such as a green olive jar or tall narrow flower vase is necessary for holding the syrup. The Fig. 3. — Small-size foo
