Essential Spice Garlic Powder is dried garlic that has been coarsely ground to a sand-like consistency. It's made by drying fresh garlic cloves in an oven, then grinding the cloves into garlic granules with a spice grinder. Garlic grows underground in the form of a bulb. (Its long green shoots produce flower stalks called scapes, which can be eaten.) Covered in an inedible papery skin, the bulb, or head as it is more often referred to, is comprised of individual sections called cloves, and there can be anywhere from 10 to 20 cloves per head. These cloves are themselves enclosed in a paper-like skin, which needs to be removed, and the pale yellowish flesh within is the part of the garlic that is used in cooking and can be cut in a variety of ways.
