Yeap, they are actually called toes. I learned that by making a HUGE mistake a few years back.
I had a recipe for a garlic black pepper sauce that was put on sirloin steak with nappa cabbage.
The recipe calls for 20 toes of garlic, I thought they meant 20 heads of garlic - let's just say even this garlic lover couldn't handle that sauce!!!
I think differant places in the country tend to use differant words.
I say head of garlic and clove of garlic. Toes was a new one for me.
