Fritessaus

The first lesson of the Dutch snackbar is that the sauce has a grammar. You don't ask for fries with mayonnaise, unless you want mayonnaise. You ask for patat met, fries with, and everyone understands the missing word. The cone arrives with a pale ribbon of fritessaus folded into the hot chips, a small national compromise between thrift, sweetness, and the need to eat standing up without ruining your coat.

The name already tells you almost everything. Fritessaus means fries sauce, no poetry, no saint, no grandmothers pretending to have invented it during a thunderstorm. But let me tell you a secret: this plain little name is exactly where the history sits. Mayonnaise had rules, fat, egg, richness. Snackbars and frietkramen, the fries stalls, needed something cheaper, looser, and lighter that still clung to potatoes. So the Netherlands did what it often does best: it made a practical thing, then became emotionally attached to it.

At home I make it without the factory's starches and stabilisers, because hou het altijd simpel, always keep it simple. Start like a mild mayonnaise, then loosen it with water and sharpen it with vinegar, mustard, lemon, sugar, and a pinch of salt. The sauce should fall slowly from the spoon, not sit stiffly like wall filler. It must cling to a fry, then slide just enough to make a mess of the last ones at the bottom of the paper cone. That, for obvious reasons, is where the best bites hide.
