1/2 cup (1 stick) butter
2/3 cup all-purpose flour
3 cups boiling milk
1/2 teaspoon salt
1 dash hot sauce
1/2 cup grated Parmesan cheese
1 cup puréed sorrel* or spinach
2 tablespoons fresh chervil leaves, or 2 teaspoons dry chervil
4 cups cooked salmon, flaked
1/4 cup grated Parmesan cheese
Preheat oven to 425 F. Melt 1/2 cup butter in heavy saucepan; stir in flour; cook over low heat 2-3 minutes, stirring constantly; pour in boiling milk, salt, and hot sauce; beat vigorously with wire whip until quite thick and creamy.
Remove from heat and divide sauce in half. Butter jelly-roll pan, 11″ x 17″ x 1″ and line with wax paper, leaving 2-inch overlap at each end; butter top of paper and dust with flour. Separate eggs. Beat yolks into 1/2 sauce mixture 1 at a time; beat in 1/2 cup cheese and 1/4 cup of the sorrel; beat in chervil. Beat egg whites until soft peaks form. Fold gently into sorrel sauce; spread out on wax paper on baking sheet; bake 15 minutes or until golden, puffed, and springy. Remove; lay sheet of wax paper on top and invert; unmold; peel off bottom paper.
Stir salmon and remaining 3/4 cup puréed sorrel into reserved 1/2 of sauce, thinning with milk if sauce seems too thick; spread 1/2 of sauce over soufflé ; using wax paper as guide, roll up jelly-roll style and transfer to serving platter; cover top of roll with remaining sauce; sprinkle with cheese and paprika and place under broiler 2-3 minutes, or until cheese is bubbly.
Yield: 9-12 servings
*About 1 pound fresh sorrel leaves, cooked.
