Omelet à la Nantua

Ingredients

Equipment Needed

• •8-inch (20 cm) nonstick or well-seasoned omelet pan
• •1-quart (1-liter) heavy saucepan
• •Heatproof flexible spatula
• •Small sauce spoon or warmed sauce jug

Instructions

1. 1

   Ready the service

   Warm four dinner plates in a 200°F (95°C) oven for 5 minutes, then switch the oven off. The plates should feel gently warm, never hot enough to continue cooking the eggs. Divide the cut tails into four equal portions of six tails each, and keep the eight fine whole tails separate. Set the omelet pan, butter, beaten-egg bowl, spatula, sauce spoon, and plates within reach before proceeding.

   Mise en place, everything placed and ready, is the true technique here. Once the eggs enter the pan, there is no useful pause.

   Warm sauce and tails

   Warm the prepared Nantua sauce over the lowest heat until it becomes fluid and glossy, without letting it boil. Add the eight whole tails for about 30 seconds, just long enough to warm them, then lift them onto a warm saucer and cover lightly. Reserve ¼ cup (60 ml / about 62 g) of the sauce for finishing. Fold the cut tails into the sauce remaining in the pan, warm them for 1 minute, and take the pan off the heat. If the sauce tightens, loosen it with 1 teaspoon (5 ml) hot water; if oily streaks appear, remove it from the heat and whisk in 1 teaspoon (5 ml) cold water until smooth. The sauce should cling lightly to the crayfish, not bury it.

3. 3

   Beat one portion

   Work one omelet at a time. Beat 3 eggs with one-quarter of the salt and white pepper until the whites and yolks are completely joined but not frothy. Air makes a puffy, dry omelet; this one should be close-grained, supple, and tender.

4. 4

   Set the eggs softly

   Heat the 8-inch (20 cm) omelet pan over medium-high heat. Add 1 tablespoon (15 ml / 14 g) butter and swirl as it foams. Before the butter colors, pour in the eggs. Stir rapidly with the spatula while shaking the pan for 10 to 15 seconds, drawing the setting egg toward the center, then stop stirring and smooth the curds into an even layer. The bottom should be set and pale while the surface remains glossy and baveuse. If the eggs seize into large dry curds, lift the pan from the heat at once and keep it moving; the gentler residual heat will finish the surface without hardening it further.

5. 5

   Fill and fold

   Spoon one-quarter of the sauced cut tails in a narrow band just below the center of the omelet. Fold the far third toward the middle, tilt the pan over a warm plate, and roll the omelet out so the final fold tucks underneath. Shape it gently into a plump oval with the spatula. If the tender surface tears, tuck the opening underneath and restore the oval with the spatula. Ça se rattrape, and the finished garnish will draw the eye where it belongs.

6. 6

   Repeat and garnish

   Wipe the pan clean and repeat with the remaining eggs, seasonings, butter, and filling. Work briskly, but don't hold the finished omelets under the broiler or return them to the oven; the warm plates are enough. Lay two whole crayfish tails over each omelet with their thicker ends touching, exactly as the entry directs. Spoon about 1 tablespoon (15 ml / 15 g) warm Nantua sauce in a fine thread around each omelet, keeping the tender golden surface visible. Serve at once. À table!

Chef Tips

• •Cooked frozen crayfish tails, thawed slowly in the refrigerator and dried well, are the honest answer when fresh freshwater crayfish aren't available. This dish truly depends on crayfish; shrimp makes a pleasant omelet, but it doesn't make Omelet à la Nantua.
• •The sauce quantity is deliberate: roughly 1 tablespoon binds the cut tails and another forms the finishing thread for each omelet. More sauce overwhelms the eggs and obscures the book's precise garnish.
• •Use an 8-inch (20 cm) pan for each three-egg omelet. A larger pan spreads the eggs too thin, and the surface sets before you can fill and fold it.
• •For anyone who should avoid softly set eggs, use pasteurized eggs and cook the center fully. The texture will be firmer, but the crayfish proportions and garnish remain unchanged.
• •Pour a dry white wine from Bugey. Its freshness suits the crayfish and cream without dragging the dish away from Nantua.

Advance Preparation

• •The prepared Nantua sauce can be made up to 2 days ahead, chilled promptly, and reheated over very low heat. If it has tightened in the cold, loosen it gradually with a teaspoon of water.
• •Thaw, drain, and portion the crayfish earlier in the day. Keep the tails covered and refrigerated, then take them out only when the sauce is ready to warm.
• •Everything except cooking the eggs can be arranged before guests sit down. The omelets themselves must be cooked at the last moment; four take only several minutes once the pan is hot.
