Matthews Bearnaise Sauce Recipes

Steps:

• Place butter in a medium glass bowl, and melt in the microwave, about 30 seconds on High. Whisk in the onion, white wine vinegar, egg yolks, heavy cream and lemon juice. Season with tarragon, parsley, salt, mustard powder and cayenne pepper; mix well.
• Return to the microwave, and cook for 1 1/2 minutes, or until thickened, stirring until smooth every 20 to 30 seconds.

Steps:

• Put the vinegar, shallots, black pepper and 1 tablespoon of tarragon leaves into a small saucepan, and set over a medium flame. Bring just to a boil, and then reduce heat to a simmer until there are only a few tablespoons of liquid left, approximately 5 minutes. Remove from heat, and set aside to cool.
• Fill a small saucepan with an inch or two of water, and set over medium-high heat to boil.
• Put the cooled shallot-and-tarragon mixture into a metal mixing bowl along with a tablespoon of water and the egg yolks, then whisk to combine.
• Turn the heat under the saucepan of water down to its lowest setting, and put the bowl on top of the pan, making sure that it does not touch the water directly. Continue to whisk the yolks until they thicken, approximately 5 to 7 minutes. You should just about double the volume of the yolks.
• Slowly beat in the butter, a tablespoon or two at a time, whisking slowly to combine and emulsify. Remove the bowl from the pan occasionally, so as not to overcook the eggs, and taste the sauce. Season with salt. If the flavor is not sharp enough, add a splash of lemon juice. If the sauce is too thick, stir in a splash of hot water. Add the remaining teaspoon of tarragon leaves, and serve.

Steps:

• Place the white wine, white-wine vinegar, shallots, 2 tablespoons tarragon, and the peppercorns in a small saucepan set over medium-high heat. Bring mixture to a boil, and cook until it is reduced to about 2 tablespoons.
• Melt the butter in a small saucepan over medium-low heat. Keep warm until ready to use.
• Place egg yolks in a copper or stainless-steel bowl that fits snugly in the top of a medium saucepan. Fill the saucepan with 2 inches of water, and bring to a boil. Whisk the yolks, off the heat, until they become pale. Add wine mixture and salt, and whisk until well combined. Gradually add 1/4 cup boiling water, whisking constantly. Place bowl over the medium saucepan of boiling water; reduce heat to lowest setting. Whisking constantly, cook until whisk leaves a trail in the mixture and sauce begins to hold its shape. Remove from heat.
• Pour the warm, melted butter into a glass measuring cup. Add to yolk mixture, one drop at a time, whisking constantly. After you have added about a tablespoon of the melted butter, you can begin to add it slightly faster, still whisking constantly. Still, be careful: If the butter is added too quickly, the emulsion will be too thin or will "break" (separate).
• Once all of the butter has been added, adjust the seasoning with the lemon juice, and stir in the remaining tarragon. If the bearnaise becomes too thick, you may thin it with a little additional lemon juice or water. If not serving immediately, place pan of sauce over a pot of simmering water that has been removed from heat, or in a warm spot on the stove for up to 1 hour. Alternatively, you may store for up to 3 hours in a clean thermos that has been warmed with hot but not boiling water.
