Omelette à l’Écossaise

Ingredients

Equipment Needed

• •8-inch (20 cm) nonstick or well-seasoned carbon-steel omelette pan
• •10-inch (25 cm) lidded skillet for butter-poaching
• •Flexible heatproof spatula
• •Instant-read thermometer
• •Four warmed serving plates

Instructions

1. 1

   Prepare the milts

   Examine the milts and remove any dark threads with the point of a small knife, keeping their delicate outer membranes intact. Pat them thoroughly dry. Mix ¼ teaspoon of the salt with the cayenne and 1 tablespoon each of the chives, parsley, and chervil, then sprinkle this seasoning evenly over the milts. Leave them for 10 minutes while you arrange the salmon.

2. 2

   Sleeve them in salmon

   Lay the smoked salmon slices flat. Set one seasoned milt across the short end of each slice and roll it once, snugly but without squeezing, so the salmon forms a complete sleeve. Trim or fold any broad overhang rather than building several thick layers. Place each parcel seam-side down; the seam will seal first when it reaches the butter.

3. 3

   Poach gently in butter

   Melt ½ cup (120 ml / 113 g) of the butter in a 10-inch skillet over low heat without allowing the milk solids to color. Lay in the parcels seam-side down and hold the butter at a quiet tremble, spooning it over them several times. Turn carefully after 3 minutes, then continue for 3 to 5 minutes, until the milts are opaque, just firm, and register 145°F / 63°C at the thickest point. If the butter begins to brown, remove the pan from the burner and transfer the parcels with the clear upper butter to a clean pan, leaving the colored milk solids behind; add a small piece of reserved cold butter and resume over lower heat. Lift the parcels onto a warm plate and cover loosely for no longer than 10 minutes.

   Poaching in butter means pale butter and patient heat. A hard sizzle tightens the milts and makes the smoked salmon curl away from them.

   Mix one omelette

   Divide the remaining chopped herbs into four portions. For the first omelette, break 3 eggs into a bowl, add one portion of herbs and a scant ¼ teaspoon of the remaining salt, then mix briskly with a fork until yolks and whites just lose their separate streaks. Do not beat in a head of foam. Mix each batch only when its pan is ready, because the herbs stay brighter and the eggs cook more evenly.

5. 5

   Cook and roll

   Melt 1 tablespoon (15 ml / 14 g) of the remaining butter in an 8-inch omelette pan over medium heat. When it foams without browning, pour in the eggs. Shake the pan while stirring rapidly with a flexible spatula, drawing the soft curds toward the center until the underside is set but the top remains glossy and creamy, about 45 to 60 seconds. Stop stirring, spread the eggs into an even oval, and set 2 warm salmon-wrapped milts aslant across the center. Fold the far third of the omelette over the filling, tilt the pan, and use the spatula to roll the remaining egg around it so the milts are fully covered. If the eggs set too quickly, lift the pan from the heat immediately and make a broad fold instead of forcing a tight cylinder. If the surface tears, tuck the soft edge beneath and turn the seam downward. Ça se rattrape.

   The filling must be ready before the eggs meet the pan. Once the omelette has reached its creamy set, there is no useful pause.

   Repeat and serve

   Invert the omelette seam-side down onto a warm plate. Wipe the pan clean and repeat with the remaining eggs, herbs, butter, and milt parcels, making four individual omelettes in all. Serve each as soon as it is rolled, or hold it on its warm plate for no more than 5 minutes. A dinner party can accept a gently staggered arrival; creamy eggs cannot accept a long wait. À table!

Chef Tips

• •Laitances de hareng (herring milts or soft roes) should be pearly, plump, and enclosed in unbroken membranes, with a clean sea smell. Order them from a fishmonger and cook them the day you collect them.
• •Fresh milts are seasonal. Jarred hard herring roe contains eggs and will not behave like milt, so it is not an honest substitution. If milts cannot be had, make an omelette aux fines herbes with smoked salmon while you wait for the proper ingredient.
• •Use flexible, thinly sliced cold-smoked salmon. Hot-smoked salmon flakes instead of wrapping, while thick slices make the filling salty and heavy.
• •An omelette baveuse (creamy at the center) depends on confident heat and quick rolling. Use pasteurized shell eggs when serving anyone who should avoid lightly cooked eggs.
• •A crisp Muscadet Sèvre-et-Maine or an unoaked Chablis suits the smoke, butter, and briny milt without crowding them.

Advance Preparation

• •Pick and chop the herbs up to 2 hours ahead, then cover and refrigerate them. Separate the smoked salmon slices and keep them chilled between sheets of baking parchment.
• •The milts may be cleaned, seasoned, and wrapped up to 30 minutes ahead. Keep them covered at 40°F / 4°C or colder, then remove them from the cold just before the butter is melted.
• •Poach all eight parcels immediately before cooking the omelettes and hold them warm for no more than 10 minutes. The omelettes themselves cannot be made ahead without losing the creamy texture that defines the dish.
