Velouté aux Grenouilles, otherwise Sicilienne

Velouté aux Grenouilles, dite Sicilienne (frog's-leg velouté), teaches the discipline of keeping a pale soup pale. Before you touch a pan, know this: the frogs' legs must poach gently in butter, white wine, and lemon without taking a spot of colour. Their delicacy is the whole point, and browning would speak over it.

The source assumes a saucier at the stove, fish stock never off the fire, delicate fish velouté already made, a mortar strong enough to pound the cooked legs, and a tammy waiting beside it. At home, one prepared batch of thin fish velouté, a blender, and a fine-mesh sieve do the same honest work. This version doubles the compact formula to make about two quarts, enough for eight first-course bowls, while preserving its proportions: thirty-six frogs' legs within the doubled range of thirty to forty, twice the wine, twice the lemon, and the full measure of best butter. The separate sauce station and the mortar are brigade scaffolding; the colourless poach, brief simmer, straining, liaison, and final butter are the dish and stay. One cook, one stove, one evening.

What reaches the bowl is ivory, smooth, quietly lemony, and glossy with butter, with no garnish because there is nowhere for weak flavour to hide. The last step decides it: temper the liaison (egg-yolk-and-cream binding) below a boil, then mount the butter off the heat. If the yolks catch or the butter oils, ça se rattrape, and the method puts the rescue exactly where you need it.
