>>189646Try this seed company for rare heirloom stuff:
http://sustainableseedco.com/If you'll be grinding your own corn, get a bag of calcium hydrate(hydrated lime) and look up how to make nixtamal for various uses of the corn. I make nixtamal then dry the corn and grind it when I need it. That's how you make masa for tortillas, tamales, and various things.
Don't limit your tomato varities to paste-type only. Many heirlooms can be used to make paste. Plus, if you are saving seeds from different varieties, you'll be making your own hybrids every so often. This helps prevent disease and gives you new and unusual tomatoes. Same goes for squashes. Most ornamental heirloom squashes are edible when young and tender and they hybridize into weird things all the time.
Get a bunch of water bath canning pots, stock pots, and a large pressure canner. Make drying racks. Go to antique stores, thrift stores, and Salvation Army and look for older hand-crank kitchen devices. Stuff like a food chopper, grain mill, meat grinder, cone strainer, food mill, etc are great buys. If you have a large production and want some of the best, get a Squeezo with extra screens (not a Victorio) and the largest pressure canner All-American brand makes. If you are making wine, cider, etc get a fruit press and apple/fruit crusher (or DIY them).
