_Prunes._——We are dealing now with a dried fruit. If you compare the raisins with the grapes in Fig. 26, you will see how much water is lost in the drying process. The same difference would be evident if you had pictures of a fresh plum and a prune, side by side. This water must be supplied in the process of preparation. The best way to accomplish this is by soaking the prunes many hours, say over night. Prunes have a most undeserved reputation, because they are not well cooked, and at some tables are served too often. With this one new step introduced you may plan the cooking of the prunes, from what you know of apple sauce. The slower and longer the process, the better. The cheaper kinds of prunes will be very satisfactory, with the soaking and slow cooking. What is the sensible thing to do in regard to sugar? If on some occasion you would like prunes to be unusually nice, remove the stones carefully, and in their places slip in seeded raisins which have also been soaked and gently stewed. _Other dried fruits_ may be treated in the same way. Apricots and peaches yield delightful flavors when carefully prepared; and dried apples are also excellent. PRESERVATION OF FRUIT AND OTHER FOODS The preservation of fruit and other foods has been a household industry for generations, and it is now an important commercial industry. The old-time farm had its smokehouse where hams and beef were “cured,” the barrel of brine stood in the cellar for pork and corned beef, apples and corn were dried for winter use, and rows of preserve jars stood upon the shelves. Food was preserved by simple processes long before the reason for the decay and spoiling of food was fully understood, but with larger knowledge and better appliances, we now preserve food more effectively and in quantities larger than were possible in former days. Fruit is the food material now most commonly preserved in the home kitchen. Vegetables need to be subjected to heat for a much longer time than fruit, and many people prefer to buy canned vegetables rather than to go to the trouble and expense of canning them at home. Where there is an oversupply of vegetables in the home garden, it is sometimes economy to can them, and this may be done if care is exercised. The cost of fuel and labor must be counted in, when studying the question of home preserving versus buying the canned product. Whatever the food material, and the process, the principles of preservation are the same for all. =Why does food spoil?=——The decay and moldiness of fresh fruit are matters of common observation; and the housekeeper knows that mold is liable to cover the top of a jelly glass, and that a can of fruit will ferment at times, even to the point of bursting the can.
