But in hard times, its nice if you already know how to cold pack for canning...
The good part is all the equipment you use is reuseable the following year with the exception of the sealing lids...I use parafin on the jam's. Tomatoes are easy canning so are peaches, pears, cherries etc. Veggies are not too practical for the cold pack method. Almost need a pressure cooker for your canning veggies...Can your spaghetti sauce without meat. Can be cold packed, add meat when fixing it for dinner...
Haven't canned in decades but once you do it for years, like riding a bike, you don't forget...
Canning meat isn’t that difficult. Home canned chili - yumm. My bunch pig out on homemade jerky.
Because of their high acidity, tomatoes can be canned in a homemade solar oven.
