I do not like using the jarred garlic you can purchase in the grocery store. I don't like the flavor and I really dont think it takes much extra time to prepare fresh, especially if you have a hand held grater. That may be the only thing I've ever taken away from Rachel Ray! I know, I know you love her! Sorry, I just can't handle her! Ick!
Anyway, it is very difficult at times, well, more often than not, to find fresh garlic at the grocery store. It is usually black on some parts, not tight together, but has cloves hanging off. Ew! So, when the grocery store has great looking garlic I buy a ton of it. I bring it home and if my bf's kids are around they LOVE LOVE LOVE to peel the garlic in the little contraptions I have, so I let them do it! If not, I go for it. It's fast and easy to do and ensures I always have fresh garlic in the fridge ready to use.
Take your desired amount of garlic cloves. Place in a food processor or blender and pulse until chopped in tiny pieces. Transfer to a tupperware OR glass jar. Add just enough olive oil to make it moist and store in the fridge.
Viola!
