Ask MetaFilter thread from someone who loves french fries but is uncomfortable dipping them in ketchup any more because it is such a heavily processed food, thus offends his current eating philosophy. How’s that for congruity? In any case, he asks what he should use instead, and there are some interesting responses. The suggestions are pretty well divided between exotic, mostly Asian, sauces, which I suspect are often as industrial as American ketchup; and some surprising simple alternatives.
