You can also buy powdered potatoes reconstituted and stored in a can of hydrogen peroxide and sulfites for 10 years.
Heck, I don’t even have a fridge. I have 20 different powders in my lab and
I just mix with water to create whatever food I want. Yesterday we all had hamburgers
on a bun. I mixed the hamburger powder, so I had hamburgers, but for the bun
I needed to wait until it rose. Making the pickles was tough though… I needed a lot
of Green #60 to blend with the Yellow #40 and 41 to get the right color.
