Only one fruit or one vegetable should be taken up at a time, for the preparation necessarily varies slightly, and the different methods will prove confusing. It is not necessary to confine the choice of fruits and vegetables to those mentioned in the recipes included here. The teacher will find it better to base her instruction on the products of the particular time and place. The principles of canning should be taken up at some other period, if possible, in order that the cooking lesson may be devoted entirely to the practical work. RECIPES _Canned Tomatoes_ (Open-kettle Method) Scald and peel the tomatoes. Boil gently for 20 minutes. Sterilize the jars, covers, and rubbers. Stand the jars on a cloth in a pan of hot water or on a board or wooden table. Fill the jars with hot tomatoes, being careful to fill to overflowing and to expel all air bubbles from the jar. Adjust the rubbers and covers. Seal and allow to cool. Test, label, and set away in a cool, dry, dark place. (Cold-pack Method) Scald in water hot enough to loosen the skins. Plunge quickly in cold water and remove the skins. Pack whole or in pieces in the jars. Fill the jars with tomatoes only. Add 1 level teaspoonful of salt to each quart. Place the rubber and cover in position. Partially seal, but not tightly. Place the jars on a rack in a boiler. Pour sufficient warm water into the boiler to come half-way up the jars. Place the filled jars on the rack so as not to touch one another, and pack the spaces between them with cotton, to prevent the jars striking when the water boils. Sterilize for 22 minutes after the water begins to boil. Remove the jars from the boiler. Tighten the covers. Invert to cool, and test the joints. Wrap the jars in paper to prevent bleaching and store in a cool, dry, dark place. This method of cooking is also called "The Hot Water Bath". _Canned Grapes_ (Open-kettle Method) 6 qt. grapes 1 qt. sugar 1/2 c. water Pick over, wash, drain, and remove the stems from the grapes. Separate the pulp from the skins. Cook the pulp 5 minutes and then rub through a sieve that is fine enough to hold back the seeds. Put the water, skins, and pulp into the preserving kettle and heat slowly to the boiling-point. Skim the fruit and then add the sugar. Boil 15 minutes. Put into jars as directed. Sweet grapes may be canned with less sugar; very sour grapes will require more sugar. _Canned Peaches_ Choose firm, solid fruit. Scald long enough to loosen the skins. Peel and cut in halves. If clingstone peaches are used, they may be canned whole. Pack the fruit into sterilized jars, fill with boiling syrup (1 c. sugar to 1-1/2 c. water). Then put on the covers loosely and place on wooden racks in the boiler. Sterilize in hot water bath for 20 minutes. Remove the jars and tighten the covers. Invert to cool, and test the joints. Wrap the jars in paper to prevent bleaching; then store. _Canned Beets_ (Single Process)
