1 c. mayonnaise
1/4 c. heavy cream
1/4 c. chili sauce
1 tsp. Worcestershire sauce
1 tsp. fresh lemon juice
3/8 tsp. salt
1/8 tsp. cayenne pepper
2 tbsp. very finely chopped white onion

Combine the ingredients and mix very thoroughly, being sure to mix the onions well into the sauce.

Refrigerate for a few hours before serving so all flavors blend.

Good on shrimp, crab, and seafood cocktails as well as Doug's Crabcakes.
