Peel and trim cloves of garlic. Place in a small saucepan and add oil.

Place over very low heat so the garlic just barely bubbles. If needed, move the saucepan off the edge of the burner, or use a heat diffuser, to keep keep the heat low enough.

Let simmer for about 40 minutes, or until garlic cloves are very tender and can be pierced easily with a sharp knife.

Transfer to a small jar and seal. Store in the refrigerator.
