4. The jars, covers, and rubbers should be put into pans of cold
water, and the water should be brought to the boiling point and allowed
to boil for 15 minutes or more while the fruit or vegetables are being
prepared for canning. They should be kept in the hot water until the
food is ready to be placed in them. In the one-period cold-pack method,
it is not necessary to boil the jars, rubbers, and covers, but this may
be done if desired.
To produce good-looking jars of food, the fruit or vegetables to be
canned should be graded to some extent; that is, the finest of the
fruits or vegetables should be separated and used by themselves, as
should also those of medium quality. Often it is wise to use the poorest
foods for purposes other than canning. The food may then be canned
according to the chosen method, but by no means should methods be mixed.
In handling the product after it has been cooked by the open-kettle
method, any spoon, funnel, or other utensil must be thoroughly
sterilized in the same way as the jars and their covers and rubbers;
indeed, no unsterile utensil should ever be allowed to touch the food
when a jar is being filled.
