Out of fresh garlic? Use 1/8 teaspoon garlic powder for each clove. Stir it into the liquid so it spreads evenly, then taste and adjust.
1 garlic clove = 1/8 tsp garlic powder (starting point)
Good for sauces, marinades and soups. It is a starting point, so taste and adjust. Powder covers the flavor but not the texture of fresh garlic.
