“Escoffier” Devilled Sauce

Sauce Diable « Escoffier » (Escoffier Devilled Sauce) teaches one precise thing: softened butter and melted butter are not interchangeable. The butter must yield completely beneath a finger while remaining cool, opaque, and cohesive. Get that texture right and the sauce becomes satin-smooth; let the butter turn oily and the mixture slumps apart.

This is one old formula that assumed neither a saucier reducing stock nor a salamander waiting above the range. Its scaffolding was commercial: a prepared bottled sauce and a brigade needing a generous bowlful at service. At home, a wide bowl and an electric mixer do the same work. The professional entry supplies a ratio rather than a batch, so that ratio is fixed here at four cups of sauce and four cups of butter, about two quarts altogether. No flavoring has been added, and the sequence remains intact. One cook, one stove, one evening, though the stove can stay cold.

Finished properly, the Sauce Diable is pale rust-gold, piquant beneath the richness, and soft enough to melt across a grilled fish or chop without running away like plain butter. The step that decides everything is tempering both ingredients to the same cool room temperature before beating.
