Adapted from the Restaurant “Hook Line & Sinker” in Dallas, Texas. While in Dallas on business we run into the always busy Hook Line & Sinker (located at 3103 Lemmon Ave.) and order the Mexican Cocktail our favorite appetizer – you can order it “Spicy” or “Regular”. I have dreams about this appetizer way down in Lake Charles, LA (where I live) – so my boss and I went to duplicate the recipe. One of the waiters shared the tidbit about the “special” sauce! I know it sounds strange to use the soda and ketchup; trust me it is delicious!
