Hey, about the Daikon greens, how hard would it be to plant a Daikon top in a pot and grow them out in the house?
Maybe that would be a doable thing..
What you are doing sounds great :). Those are many of the kind of things I love, putting things by in the traditional ways, food preserving, etc..
As I recall, at one time there was an entire gov bivouac ration based upon green pea flour, and the Danes won a war during the snowbound European winter fortified by dry salame. Nail down your source of cooking oil and you should have it made..
