How much cinnamon should I sprinkle on my tubers clumps. I pulled five out of the crawlspace and was amazed that they are just a little dry, far from rotting. But none show eyes well enough to cut them up. So I am going to sprinkle with cinnamon and put them back in their shopping bags (plastic) and loosely close them. We'll see how the next batch goes. Back into the dungeon.
