Ketchup enhances most things.....

I couldn't agree more on the steak..
I always ask for a side of mustard when I have french fries. I mix a little bit of mustard in my catch up. Two parts ketchup one part mustard is the base for a good Southern BBQ sauce, of course with many other spices for the sauce..
I've had steaks in Colorado, Texas, Illinois, Iowa, etc etc... and been told "you won't need ketchup here..." me: "hey waitress, can you bring me a bottle of ketchup please?" :D
