The parts of fruit preservation were interesting, though I couldn't get the link to work for the section detailing preservation using salt water. I never heard of encasing unripe fruit still on the vine with mud. Burying grapes in sand with a jug overtop reminds me of "Dr. Beals Seed Viability Experiment". This ongoing experiment is over a hundred years old. Never imagined it could be used to preserve food as well.
