Recipe variations and substitute ideas

• Chili powder or cayenne — increase heat to taste.

• Lemon or lime juice — use lime in place of lemon for a brighter citrus note.
• Brown sugar — a small amount adds a subtle sweetness if desired.
• Olive oil — can be mixed in for a slightly different texture.
