Lemon & Green Onion Crab Cakes with Spicy Mustard Aioli
Why Lemon & Green Onion Crab Cakes Stand Out
What makes these citrus crab cakes different from classic versions lies in the interplay between brightness and depth. Lemon zest lifts the flavor profile, while green onion introduces freshness without dominating the delicate crab meat. Combined with a spicy mustard aioli, the dish gains complexity and character.
Key qualities that define this variation:
- Bright citrus undertones that enhance aroma
- Gentle onion sharpness for contrast
- Minimal filler to maintain texture
- Balanced seasoning with subtle heat
