One clove of garlic equates to about 1 teaspoon of chopped garlic, 1/2 teaspoon bottled minced garlic, 1/8 teaspoon garlic powder, 1/4 teaspoon granulated garlic, or 1/2 teaspoon garlic flakes. A garlic bulb has approximately 10 cloves.
A small clove of garlic is equivalent to 1/2 to 1 teaspoon of chopped garlic. A medium clove of garlic is equal to 1 to 1 1/2 teaspoons of chopped garlic. A large clove of garlic is equal to 2 to 2 1/2 teaspoons of chopped garlic. Forty cloves of roasted garlic makes about 18 teaspoons, or 6 tablespoons, of roasted garlic purée.
