Take a couple of heads of garlic, sit them in some oil with spices, and cook for an hour or two, then spread it on bread. It's great...with the right kind of garlic. With the wrong kind, you'll be praying for death, and so will everyone around you.
I've tried this a couple of times, and trial and error is not cutting it. Does anyone know a variety of garlic that is mild enough for this sort of thing, but still possible to find in a store?
