Ketchup enhances most things.....

not around here it doesn't. if you need ketchup or steak sauce to improve the taste of a steak then the steak isn't prepared properly in the first place, so yea smother it in anything needed to cancel out the incompetence of the cook.. :)

i do like dipping my fries in honey mustard...

and poutine fries done correctly are incredible.. :)
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..
