We dyed eggs today, and one batch was done in grape juice for the first time (instead of red wine). We did another with onion skins, and I made dyes from red cabbage, cayenne powder, and turmeric. Turmeric was the most annoying because of how hard it was to strain. Hopefully we'll have a couple really yellow eggs, though.
(Another project today was making fruit leather for the first time with more of my surplus grapes.)
