Diceman's Coctail Sauce
Lots of Ketchup.  Add Horseraddish and Tabasco to taste (I like my SPICY!).  Throw in some Worshestershire sauce and lemon juice.  I also throw in some Chipolte Tabasco and some Frank's Red Hot.  Then cook up some shrimp so that you have an excuse to eat the sauce.  <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> 
Now thats good. They do a LOT of shrimping here!
