Ran across an interesting article on long term storage of tomatoes in dry (sifted) wood ash. Digging around a bit more and it turns out that this isn’t actually a new idea, and that it actually works. Science abstract here (gotta track down the full text, they tried various levels of moisture). Additional info here.
Kinda cool. My problem with trying it here is the moisture content. I gotta see if I can track down the full article from the testing to see what moisture levels weren’t worth it. We tend to be pretty damp here through the fall at least.
