I just turned 5 lbs of onions into a few ounces of onion powder. I added some salt to inhibit bacterial activity. I did the same thing with about 5 lbs of habanero peppers recently. That was kind of miserable work. I want to see about drying about potatoes next. I’m thinking dehydrated hash browns. I found this web site here: https://www.usaemergencysupply.com/information_center/storage_life_of_foods.htm#link9
they have lots of good info on the subject. I’m going to buy at least 50 lbs of their mixed beans and store them in my basement. they should be good for a decade. I’m looking at their cheeses and milk products too.
Very cool! Thanks for the tips and the link!
