Kerriesaus (Dutch Curry Mayonnaise)

Kerriesaus is what happens when a seafaring country grows casual about spices. The Dutch once counted nutmeg, mace, cloves, and cinnamon like treasure, then a few centuries later stirred a yellow spoonful of kerriepoeder into mayonnaise and handed it to you beside kibbeling at a kraam, a street stall. History and cookery, they cannot be separated. Sometimes they arrive in a silver archive box. Sometimes in a plastic cup next to fried fish.

The name already tells you enough, if you listen politely. Kerrie is the Dutch kitchen's word for curry powder, a colonial and commercial blend rather than one spice, shaped by the British word curry and by the Indo-Dutch table, with older roots in South Asian kari, sauce or relish. But let me tell you a secret: this sauce is not trying to be an Indonesian kari, and it should not pretend to be one. It is a Dutch snackbar sauce, mild, golden, a little sweet, a little sharp, made for salt and fat and the clean bite of hot fish.

So we keep it honest. Hou het altijd simpel, always keep it simple. Use a curry powder that smells alive, bloom it for half a minute in a spoon of neutral oil if it tastes dusty, then cool it before it meets the mayonnaise. That tiny warm step wakes the spices without turning a cold sauce into cooking theatre. Lemon brings the quay back into the room, mustard gives backbone, and a little honey rounds the edge. Then let it rest, because even a sauce sold in a hurry tastes better when the spices have had time to introduce themselves.
