Oeufs en Gelée — Eggs in Aspic

Oeufs en gelée is a classical garde manger showpiece in which soft-poached eggs are suspended in crystal-clear aspic within individual moulds, often garnished with tarragon leaves, truffle slices, or ham julienne to create an elegant, self-contained cold first course. The eggs (Gallus gallus domesticus) must be impeccably fresh — no more than 3 days old — as the albumen's viscosity decreases with age, resulting in ragged whites. Poach in water acidulated with 15 ml white wine vinegar per litre at 80–82°C for exactly 3 minutes and 30 seconds to achieve a fully set white with a fluid, molten yolk. Transfer immediately to an ice bath at 0–2°C to arrest cooking. Trim any trailing wisps of white with scissors for a clean, ovoid shape. The aspic — a fully clarified fond blanc de volaille or veal consommé set with gelatin at 3–4% concentration — is cooled to 28–30°C, just viscous enough to coat evenly without running. Begin by pouring a 5 mm base layer of aspic into each chilled dariole mould or oval ramekin and refrigerate for 10 minutes until just set. Arrange decorative garnish on this layer: blanched tarragon leaves (Artemisia dracunculus), truffle diamonds (Tuber melanosporum), or thin-cut jambon de Paris. Set garnish with another thin layer of aspic and chill 10 minutes. Place the trimmed poached egg, yolk-side down, in the centre, and fill the mould to the brim with aspic at 28–30°C. Refrigerate for minimum 4 hours. To unmould, briefly dip the exterior in warm water at 35°C for 3–5 seconds, invert onto a chilled plate, and serve immediately. When cut, the yolk should flow in a controlled stream, contrasting with the trembling clarity of the surrounding gelée.
