Mousseline Sauce Recipes

Steps:

• For the mousseline sauce: Place the egg yolks and citrus juices in a bowl over simmering water or in a double boiler. Cook, whisking, until thick and frothy with a ribbonlike texture, about 10 minutes. Remove from the heat and whisk in the butter to emulsify. Season with salt and pepper. Set aside.
• For the leeks: Thinly slice the leeks into matchsticks. Add the butter to a large skillet over medium heat, and cook until brown, 5 to 6 minutes. Add the leeks and saute until translucent and soft, 2 to 3 minutes. Season with salt and pepper. Set aside.
• For the asparagus: Bring a medium saucepan filled with cold water to a simmer, then add the salt. Cut the tough ends from the bottoms of the asparagus and peel the stalks. Blanch the asparagus in the simmering water for 3 to 4 minutes. Meanwhile, add ice to a medium mixing bowl filled with cold water. Add the blanched asparagus to the ice water to stop the cooking. Once the asparagus have chilled, remove from the ice water and pat dry.
• Arrange the leeks on a serving platter. Lay the asparagus on top. Glaze the asparagus with the mousseline sauce. Serve with the remaining sauce on the side.

Steps:

• For the sauce: Heat the butter over low heat. Saute the carrots and onions for 2 minutes. Chop the shrimp, add them, turn up the heat and fry until they turn bright red, about 3 minutes. Flame with the Cognac. Add the wine and reduce by half. Add the stock, bring to a boil and reduce to a simmer. Add the tomato paste, cayenne, paprika, bay leaf and thyme and cook for 30 minutes. Stir in the cream and let bubble a further 10 minutes. Pull out the bay leaf and thyme and blitz the mixture in the food processor. Strain through a fine-mesh sieve. Bring the sauce back to a boil in a saucepan, reducing to sauce consistency. Season with salt and pepper.
• For the fish: Put the fish, cream and egg in a food processor and whiz just a few seconds to form a paste. Stir in the parsley, salt and pepper and chill for 30 minutes.
• Before serving, preheat the oven to 350 degrees F/180 degrees C. Butter 6 ramekins (or a terrine) and put a round of parchment in the bottom of each. Fill the ramekins with the fish mixture. Set them in a baking dish and pour boiling water around to come halfway up the sides. Bake until just set, about 20 minutes.
• Unmold onto warm serving plates. Spoon the sauce over the top, and serve hot.

Steps:

• Snap the ends off the asparagus. Then, using a vegetable peeler, peel about 2 inches off the thickest part of the stems.
• Bring a big pot of water, with the salt and the sugar, to a boil. Drop in the asparagus, and cook for about 15 minutes, depending on the thickness. Pierce with a fork to see if they are tender; white asparagus should be cooked softer than green asparagus. Drain, and set aside.
• Meanwhile, to make the mousseline, separate the egg, and put the yolk in the bowl of a food processor fitted with a steel blade. Add the mustard, red-wine vinegar, and salt and freshly ground pepper to taste. Pulse to combine. With the motor running, gradually drizzle in the oil until it emulsifies and you have a thick, creamy mayonnaise.
• Beat the egg white to stiff peaks. Mix half of the beaten egg white into the mayonnaise, then gently fold in the other half to make a very fluffy mousseline. Serve the hot asparagus with the mousseline on the side.
