I used to love french fries dipped in a chocolate sundae. I had a girlfriend that added catsup first.
The most sophisticated chick I ever knew, she ran PR at the local art museum, turned me on to dark mustard on fried potatoes.
Russian salad dressing used like barbeque sauce, poured into a crockpot with a big deer roast is excellent.
When I smoke a turkey, I inject a combination of grape jelly, lemonade, butter and curry powder. Yum.
