Use thin syrup with sweet fruits. Use medium syrup with sour fruits. Thick syrup is used in candying and preserving.
SPECIAL INSTRUCTIONS FOR CANNING FRUITS
Apples
Wash, pare, quarter or slice and drop into weak salt water. Blanch 1½ minutes, cold-dip, pack into jar and cover with water or thin syrup. Put on rubber and top and adjust top bail or screw top on with thumb and little finger. Sterilize for 20 minutes in hot-water bath.
Apples shrink during sterilization and for this reason economy of space is obtained by canning them in the form of sauce instead of in quarters or slices. In canning sauce fill the jars with the hot sauce and sterilize 12 minutes in hot-water bath.
Apricots
Use only ripe fruit. Blanch 1 to 2 minutes. Wash, cut in half and remove pit. Pack in jar and cover with medium syrup. Put on rubber and top and adjust top bail or screw top on with thumb and little finger. Sterilize 16 minutes in hot-water bath. Remove, complete seal, cool and store.
Blackberries
Wash, pack closely and cover with medium syrup. Put on rubber and top and adjust top bail or screw on top with thumb and little finger. Sterilize 16 minutes in hot-water bath. Remove, complete seal and cool.
