Once this sauce is completed, it is best to refrigerate it at least one hour before serving    To begin mix 2/3 cup ketchup with 3 Tbsp horseradish in a bowl    Add 2 tsp of finely grated shallot and 1 1/2 tsp chipolte hot sauce or chipolte pepper    add 1 tsp apple cider vinegar and 1/4 tsp Worcestershire sauce    salt and pepper to taste    my favorite is to serve chipolte horseradish sauce as a side with seafood
