Collect and clean the peels

• Save the papery onion skins instead of discarding them.
• Rinse and pat them completely dry, removing any dirt or damaged pieces.

Dehydrate the peels

• Spread the peels in a single layer on a baking tray.
• Dry them in a low oven until brittle and fully dried.

Grind into powder

• Let the dried peels cool, then grind them in a blender until fine.
• Sift the powder to remove any coarse bits.

Store

• Transfer the powder to an airtight jar and keep it in a cool, dry place.
• Use it to add an onion flavor kick to any recipe.
