Hard-boiled yolks, mustard, and patient oil make sauce gribiche, a cool, softly textured emulsion sharpened with capers, gherkins, three herbs, and fine rods of egg white for cold fish.
Sauce gribiche (a cold hard-boiled egg emulsion) teaches one clean lesson: an emulsion begins with a stable base, not with the oil. Work the cooked yolks and French mustard absolutely smooth first, and the sauce will accept its oil patiently. Rush that foundation and you chase little yellow lumps around the bowl all evening.
The original formula assumed a saucier working six yolks and a pint of oil in a broad basin. For one cook, that brigade quantity is scaffolding, so this version makes one-third of it in a sturdy mixing bowl with a fork and a small whisk. The proportions, the cooked-yolk foundation, and the order of the oil remain untouched because those are the dish. One cook, one stove, one evening.
The finished gribiche should be pale ochre and softly spoonable, with mustard beneath the richness, little sparks of caper and gherkin, green herbs, and distinct white julienne. Before the first drop of oil goes in, make the yolk and mustard paste completely smooth. That is the step that decides the sauce.
