Minced garlic is when peeled garlic cloves are minced into fine, small pieces that are less than ⅛-inch on all sides. To cook with garlic, you can slice it, chop it, or sauté it in whole cloves.The more time that garlic gets to break down, the more enzymes are released and the more allicin is produced. More time equals more flavor, but it can also become overpowering if left sitting too long.
