Preheat oven to 350 degrees. Take a small baking dish that is about an inch or two deep. I used a dish that is about 5 inches square and an inch and a half deep. Pour in 3/4 cup water and some vinegar (receipe recommended using white wine, I used white) - maybe a teaspoon. Take a clove of garlic, chop the top off with a really heavy knife in one fell swoop so the tips are exposed. Removed the losest layer of paper. Drizzle the top with olive oil and then cap with aluminum foil.
Bake for an hour.
There are a lot of purposes for roasted garlic. I used it for gourmet sandwiches and then I just ate it. I think I'll probably make a batch before big dinner parties and before thanksgiving, and just use it in everything.
