Man, that looks delicious. Moar garlic, I say.
I roast my own garlic and use it daily.
Wrap three heads of garlic, whole, in aluminum foil.
Place directly on oven rack.
Bake for 30 minutes at 350*F
Let cool.
Peel and place cloves in a jar.
Pour enough olive oil into the jar to cover cloves.
Ta da.
Keeps in the refrigerator for as long as I need it to - usually a couple months. Bonus is that the olive oil becomes garlic oil that I use for sauteeing or for tossing with cut up potatoes and then roasting them. Mmmm.
