2: Add 1 teaspoon Brandy (Cognac or Armagnac), 10 drops Tabasco and 1 teaspoon tomato paste. Mix thoroughly, the best way is to reuse the blender that you used for making mayonnaise.
3: Your cocktail sauce is ready.
Remarks
If you don't have tomato paste, you can use ketchup instead, it has less flavour, but it will give you the light pink colour of cocktail sauce.
