When you want the foundational flavor-layering onion's taste in a dish without the need to cut them up fresh, onion powder is a great alternative that lacks the pungent sulfur flavors and aromas that fresh onions carry. Use in just about any cuisine or dish where you want the flavor of onion, and pair with other spices such as Toasted Garlic Powder or Cumin to create a unique flavor profile in your dish.
