Melted Butter

Beurre fondu, melted butter, teaches restraint. Its one true thing is this: melting is the finish, not the beginning. You want butter just warm enough to become fluid while its water and milk solids remain held in the golden fat. Let it sit over heat until it clears, and you have beurre clarifié, useful elsewhere but stripped of the fresh flavor and soft grace this sauce owes boiled fish.

The original entry assumed a saucier could make an unmeasured service portion at the last instant while another hand drained the fish. At home, the honest equivalent is a small saucepan, 1/2 cup of butter for four people, and every plate ready before the flame is lit. The entry's little salt and few drops of lemon are measured here for consistency; no stockpot, reduction, roux, or salamander belongs to this preparation. Those are scaffolding for other sauces. Here the last-minute melting is the dish. One cook, one stove, one evening.

Keep the heat low and pull the pan away while the final pieces are still visible. Residual heat finishes them. If a clear ring forms, cold butter and the lemon drops can bring the emulsion back. Ça se rattrape. The step that matters most is serving the beurre fondu before it has time to separate.
