Next year I'm planning on having a garden since it will be mine and df's first house with a yard. lol Well my main purpose for the garden is so I can/ freeze veggies, plus I grew up eating what I grow and I really do believe it's better than store bought. Well I talked to my grandma who's canned for many years but she's set in her ways and thinks that's how everyone should do it. She swears by a pressure cooker.
My question is, is a pressure cooker neccessary for canning things? If it helps I plan on canning tomatoes and varius sauces made from tomatoes, green beans, pickles, pickled okra and so far that's all I've planned for now.
