Have tried ketchup and syrup (separately) on scrapple but prefer neither. Ketchup on fries and burgers. Mustard on hot dogs. I'll put ketchup on a homemade 'minute steak' chease steak, but don't think I have ever done it on a good one. Either do cheese steak 'hogie' Letuce tomatoes mayo, or onions peppers shrooms and sauce..
