SAUCE BEARNAISE MINCEUR Bonus Minceur Béarnaise Sauce FRENCH YIELD: One cup 1 teaspoon polyunsaturated margarine or oil. 2 teaspoons cornstarch or arrowroot. 1/2 cup chicken consommé or broth. 1 egg yolk, at room temperatures 1/8 teaspoon salt. 1/8 teaspoon white pepper. Bouquet de Vinaigrette, consisting of: 1/4 cup wine vinegar, preferably tarragon, or sherry vinegar. 1/4 cup white wine or dry vermouth. 1 tablespoon minced shallots or scallions. 2 tablespoons fresh minced tarragon, or 1 tablespoon dried. 1/2 teaspoon minced fresh parsley, or 1/4 teaspoon dried. 1. Prepare the BOUQUET DE VINAIGRETTE by placing all its ingredients in a saucepan and bringing them to a boil. Reduce the heat to medium and cook about 15 minutes, until the mixture is reduced to about 2 tablespoons of concentrated BOUQUET. 2. Blend together the cornstarch and margarine in a double boiler or BAIN-MARIE, and add the consommé. Cook over medium heat for about 5 minutes, stirring constantly until thickened. 3. Beat the egg yolk about 1 minute and blend with 2 tablespoons of the thickened sauce before adding it gradually to the remaining sauce. Continue to cook over low heat for 2 minutes, stirring constantly. Remove from heat, and blend in the BOUQUET DE VINAIGRETTE. Add salt and pepper to taste. BONUS IDEAS: You can prepare Bonus HOLLANDAISE SAUCE in virtually the same way, but instead of preparing and blending in the BOUQUET DE VINAIGRETTE, substitute 1 teaspoon of fresh lemon juice; blend it into the sauce after removing it from the heat. The BEARNAISE SAUCE can be enriched in a number of ways. Try adding 1/4 teaspoon of nutmeg to the BOUQUET DE VINAIGRETTE; or, after blending, add 1 teaspoon ofmeat glaze (page 110-11) and whisk the sauce lightly for 5 seconds. Especially for use with grified meats, consider adding 2 1/2 tablespoons of tomato paste to 1 cup of the BERNAISE, to prepare CHORON SAUCE, or BERNAISE AND TOMATO SAUCE. Because of the egg yolk, this is a Bonus recipe; however 2 egg whites whisked for 1 minute until foamy may be substituted for the egg yolk. From The New French Cooking by Armand Aulicino 1976,
