What Is Onion Powder Made from Skins?
Traditional onion powder is made from the whole bulb, but this twist uses the often discarded outer onion skins—those papery layers that are surprisingly full of flavor and antioxidants. Used in culinary traditions around the world, onion skins are packed with quercetin, a powerful antioxidant, and bring earthy, umami-rich notes when dried and ground. This method is not just smart—it’s kitchen alchemy.Onion powder
