Open kettle or hot water bath? I've not talked with anyone that canned
tomatoes open kettle; that was usually such things as jams and jellies as
well as pickles.


Open kettle i.e the tomatoes are cooked before placing in the can, Hot water
bath usually refers to cold pack. Open kettle was the favorite method of the
older generation (my mother was born in 1894) and I still prefer them.
