Chef’s Secret

To reduce the pungency of raw purple onion, slice it thinly and soak in ice water for 15-30 minutes before serving.

Substitutions

Best Match

Yellow Onion

1:1

Good for cooking, but more pungent and less sweet when raw. Lacks purple color.

White Onion

1:1

Crisper and sharper than yellow onions, good for raw applications but still lacks color.

Shallot

2-3 small shallots : 1 medium onion

Milder and sweeter, with a hint of garlic. Excellent for dressings or delicate dishes.

Scallions (green parts)

1 bunch : 1 medium onion

For a milder onion flavor and green color, suitable for garnish or quick cooking.

Buying Guide
