| With apologies to your Mother, salt in canning tomatoes is optional only, not required, and AFAIK it never has been required. The approved recipes all say "if desired". We can all our tomatoes without added salt and have for years. That way they can be used in many different recipes. Added acid in the form of bottled lemon juice or citric acid IS required. Dave |
