This garlic powder contains only garlic. It is a completely handcrafted product, peeled and washed by hand and then dried and ground. This variety (Chesnok Red) is a moderately-flavored, very enjoyable powder.
Store away from heat, light and moisture.
Garlic powder is a very different ingredient than fresh garlic, and has some applications where it works better than fresh. Any time high heat is being used (grilling, frying), powder helps avoid the astringent taste of burnt garlic. In marinades, rubs or dredges, powder ensures that the flavor permeates more evenly. It adds its own complexity and umami flavor... and no one says you can't use both, to layer flavors in a complex ragu, for example.
