French fries
Plain french fries made from fresh potatoes are low in histamine with no significant histamine-related concerns.
Potatoes themselves are low histamine, and frying in fresh oil doesn't introduce histamine into the equation.
-
Oil quality is worth considering — repeatedly reused frying oil degrades over time and produces various breakdown compounds; while this isn't a well-established histamine-specific concern, it's a reasonable general consideration when eating out
-
Watch the extras — plain fries are fine, but ketchup (tomato-based, often with vinegar) and seasoning blends with additives can raise the histamine load of the overall snack
Ordering fries plain or with low-histamine dips tends to keep things more manageable.
