This zesty dip for shrimp and other seafood isn't just cheaper than bottled cocktail sauce; you can also dial up the heat to taste with more horseradish or hot red pepper.
In a small, nonreactive bowl, combine all the ingredients and stir until well blended. Cover the bowl and refrigerate for at least 1 hour before serving.
Store in an airtight container in the refrigerator for up to 1 month. Makes about 1 cup.
