I was cleaning out my cold cellar (43 F), and I found some old dried garlic stalks with bulbs. Not sure what it was doing there, or how long it had been there, I decided to break off the heads for eating or planting and compost the stalks. Turns out, it was last garlic that was grown by my grandfather, who died in 2008, and had been stored there since for sentimental reasons. The garlic itself looked in pretty good condition, no visible rotting or mold. I feel really bad for breaking it, and don't want to just throw them out. Are they safe to eat? Could I plant the cloves? Any other creative ideas of what to do with this sentimental garlic?
