Norwegian Duchesses

Duchesses norvégiennes (little Norwegian-style stuffed choux) teach the discipline of temperature. The choux must be dry and completely cool, the Kilkis butter soft enough to pipe but firm enough to hold, and the jelly barely fluid. Warm jelly over warm butter gives you a greasy, sagging mouthful. Cool components give you crisp pastry, a melting center, and a fine translucent glaze.

The original entry assumed a pastry station with ready choux, a garde-manger (cold station) holding fish butter and clear jelly, and enough hands to fill a banquet tray. This home version makes 24 with one saucepan, one oven, and a small processor or sieve. Because the entry supplies no brigade quantity, it uses equal weights of drained Kilkis and butter, enough to form a smooth, distinctly fish-led purée. Separate stations and hundreds of pieces were scaffolding. The choux, the Kilkis-and-butter purée, and the jelly glaze are the dish, so none disappear.

When they are right, the little crowns are deep butter-gold, hollow beneath the crust, and glossy with the thinnest coat of jelly. The cured sprat strikes first, then the butter rounds the salt and smoke. Dry the choux until their bases feel firm and their centers hollow before you fill them. That is the step that decides the dish.
