Poached Eggs (Oeufs Pochés)

Poached eggs appear throughout French and British cookery histories. The classical French application — oeufs pochés — was codified in Escoffier's guides as the foundation for dozens of named preparations. The acidulated water technique is French classical practice: a small amount of white wine vinegar assists the white protein in coagulating quickly and cleanly around the yolk, before the white has time to disperse through the water.

A whole egg slipped from its shell into barely trembling acidulated water and cooked until the white is set and the yolk completely liquid — contained in a firm white envelope that yields under pressure and releases a flowing golden centre. The most elegant egg preparation in the classical repertoire and the one that most precisely reveals the quality of the egg it begins with. An old egg makes a ragged poached egg. A fresh egg makes something close to perfect.

The poached egg is a delivery system for the yolk — a concentrated emulsion of fat, protein, and lecithin that carries and releases flavour with extraordinary efficiency. When the yolk runs, the fat-soluble aromatic compounds in whatever accompanies it dissolve into the yolk and are amplified on the palate. Hollandaise and poached egg on eggs Benedict is not merely rich — the hollandaise's lecithin and the yolk's lecithin belong to the same chemical family and merge seamlessly into a unified fat phase that carries every flavour simultaneously. As Segnit observes, truffle and egg is one of the great pairings of the entire flavour world: truffle's volatile sulphur compounds — dimethyl sulphide, bis(methylthio)methane — are fat-soluble and dissolve into the yolk's lecithin with extraordinary efficiency, while the egg's own mild sulphur register provides an aromatic scaffold that the truffle's more complex sulphur compounds can build upon. The pairing is chemical, not accidental.
