Process for preserving foods for storage

What You Need to Know

Home canning or bottling, also known colloquially as putting up or processing, is the process of preserving foods, in particular, fruits, vegetables, and meats, by packing them into glass jars and then heating the jars to create a vacuum seal and kill the organisms that would create spoilage.

Steps

    Italian Tomato Passata (Italy): Preserves summer tomatoes for year-round use in sauces

  2. 2.

    German Sauerkraut (Germany): Lacto-fermentation followed by canning for long-term storage

  3. 3.

    American Fruit Jams (United States): Preserves seasonal fruits with sugar in shelf-stable form

Common Mistakes
