Shrimp Remoulade Sauce

This was Dad's favorite sauce for boiled or steamed shrimp. The last couple of years I've served it as a first course for our Christmas dinner.

1/3 cup horseradish mustard
3/4 tsp. Cayenne pepper
1/3 cup tarragon vinegar
2 cloves garlic, finely chopped
3 tbsp. catsup
2 tbsp. paprika
1 tsp. salt
1/2 cup olive oil or salad oil
1/2 cup chopped green onions and tops
1 lb. peeled, cooked shrimp


Combine all ingredients except shrimp and shake well. Chill in refrigerator for several hours. Place shrimp on chilled lettuce and drizzle sauce on top. For festive occasions serve shrimp with remoulade sauce in champagne glasses.
