Follow-up to the French Fries thread...

Ketchup is my traditional choice. But I would also use bbq sauce or mustard as alternatives. The cheese sauce would be good, but that's rarely available. Some kind of garlic/butter/cheese mixture would be cool, too.

I never thought I would eat mustard on fries until one year I started a new high school and discovered the cafeteria had no ketchup available. To me that was just unheard of. But they did have mustard and before long I developed a liking for it.
