Chef tips

To keep the onions crunchy and vibrant purple, use warm but not boiling water. Kids can help carefully pour the liquid into the jar and watch the magical color change happen in minutes. For a refreshing twist, add a small slice of beet for a deep pink hue, or some allspice berries. It's the perfect topping for meat sandwiches, fresh salads, or a juicy homemade burger.
