Suprêmes de Volaille Écossaise

Suprêmes de Volaille Écossaise (poached chicken breast fillets with Sauce Écossaise and butter-bound French beans) teaches one true thing: gentleness is an active technique. The poaching liquid must barely tremble. Let it boil and the delicate breast tightens before you have time to argue with it.

The original entry assumed a saucier tending the finished Sauce Écossaise, a stockpot never off the fire, and enough hands to poach the poultry while another cook finished the beans. At home, prepare the named sauce first, then use one wide pan, one saucepan, and an instant-read thermometer. The separate stations and holding pans were brigade scaffolding, so they can go. The gentle poach, the sauce kept whole, and the beans cohered with real butter are the dish, so they stay. A salamander has no work here; browning the top would betray the pale delicacy the recipe intends. One cook, one stove, one evening.

When it lands on the platter, the suprêmes should be tender and pearl-pale beneath a generous coat of sauce, with bright green beans gathered around them in buttery little heaps. Keep the poaching liquid below a simmer from the moment the chicken enters. That is the step that decides everything.
