Kip in Mosterdsaus

In my grandmother's second notebook, the grand dishes have careful titles and the weeknight ones have practical little names. Kip in mosterdsaus, chicken in mustard sauce. No poetry. No ceremony. But let me tell you a secret: Dutch home cooking often hides its intelligence in plain clothes, and this dish is one of those quiet conspiracies.

The name already tells you the whole method. Kip is browned first, because pale chicken in cream is a sad little sermon, and mosterdsaus needs the brown bits at the bottom of the pan to become more than cream with ideas. The mustard should be Groninger mosterd, the coarse northern kind, with seeds that pop under the teeth and a vinegar bite that cuts through richness the way a clean knife cuts butter.

There is an older word hiding in that jar. Mustard comes by way of French from the Latin mustum ardens, burning must, because crushed mustard seed was once mixed with young grape must until it bit back. History and cookery, they cannot be separated, even on a Tuesday evening. Here the old fire is tamed with cream, onion, and a little stock, not silenced. Hou het altijd simpel: brown the chicken properly, soften the onion slowly, stir in the mustard off the fiercest heat, and let the sauce thicken around the meat until it coats the spoon.
