Simply add the ingredients listed below to 1 cup of mayonnaise and blend in a processor until smooth and tasty. In sauces like this htere is really no need for quantities; I have put them here as a guide but let your taste buds guide you. Remember that commercial mayonnaise is already well seasoned, so don't add salt or pepper until the very end.
Adapt this for shrimp cocktail using shredded iceberg lettuce. Or try hanging juicy cooked chilled Mediterranean shrimp like synchronized swimmers around a bowl filled with crushed ice and some of this sauce set in the middle. Traditionally lightly whipped cream was added to this sauce for an even more delicate color and texture. Try adding a little cream and a drop of rose water.
3 tablespoons tomato ketchup
1 tablespoon Worcestershire sauce
1 tablespoon Cognac
1 tablespoon sherry
dash of Tobasco sauce
pinch of paprika
This sauce has to be a delicate pale pink. Adjust the color by adding more mayonnaise or ketchup accordingly.
