Paupiettes de Poisson — Rolled Stuffed Fish Fillets

Paupiettes are thin fish fillets (classically sole or whiting) spread with a savoury mousse or forcemeat, rolled into neat cylinders, and shallow-poached in fumet and wine. The technique demonstrates the poissonnier's finesse — achieving a perfectly cooked fillet around a distinct, creamy centre, presented in a glossy sauce built from the cooking liquor. The fillet preparation is critical: place the fillet skinned-side up (the side that had skin is slightly rougher, which helps the mousse adhere), flatten gently with the side of a knife, and spread a 5mm-thick layer of mousseline (pike, sole, or salmon mousse enriched with cream) over the surface, leaving a 1cm border. Classic garnishes may be placed in the centre — a line of duxelles, a strip of smoked salmon, or a quenelle of lobster mousse. Roll tightly from the tail end toward the head, and secure with a single toothpick or simply place seam-side down. The paupiettes are then shallow-poached: stood upright in a buttered sauteuse with shallots, fumet, and white wine at one-third depth, covered with a buttered cartouche, and cooked at a gentle simmer for 12-15 minutes until the mousse is set (internal temperature 68°C, higher than plain fish because the mousse must set). The cuisson is reduced, enriched into a sauce (commonly Sauce Vin Blanc, Normande, or Mornay), and the paupiettes are napped. Each portion is sliced in half on the bias to reveal the spiral of fillet and mousse — a visual signature of the technique.
