Crab cocktail is a great appetizer - - because it looks delicious and is colorful, light and served cold.
- Process all ingredients for the sauce - ketchup, horseradish sauce, orange juice, salt, sugar, and mustard - in the blender. Transfer to a bowl and chill until needed.
- Check the crab meat to remove any remaining bits of shell. Chill.
- To serve, arrange the shredded lettuce in seafood cocktail cups, distribute the crab meat on top and spoon some sauce over the crab, 2-3 Tbs should be enough.
If you don't like it so spicy, try mayonnaise or one of its variations.
For a quick thousand islands sauce, substitute horseradish sauce with the same amount of mayonnaise and omit mustard.
