BEURRE BUTTER RECIPES

Steps:

• Boil wine, vinegar, and shallot in a 2- to 3-quart heavy saucepan over moderate heat until liquid is syrupy and reduced to 2 to 3 tablespoons, about 5 minutes. Add cream, salt, and white pepper and boil 1 minute. Reduce heat to moderately low and add a few tablespoons butter, whisking constantly. Add remaining butter a few pieces at a time, whisking constantly and adding new pieces before previous ones have completely liquefied (the sauce should maintain consistency of hollandaise), lifting pan from heat occasionally to cool mixture.
• Remove from heat, then season to taste with salt and pepper and pour sauce through a medium-mesh sieve into a sauceboat, pressing on and then discarding shallot. Serve immediately.

Steps:

• Combine the shallots, white wine, and lemon juice in a non-reactive saucepan over high heat and reduce to 2 tablespoons.
• Add the cream to the reduction. Once the liquid bubbles, reduce the heat to low. Add the butter, one cube at a time, whisking first on the heat and then off the heat. Continue whisking butter into the reduction until the mixture is fully emulsified and has reached a rich sauce consistency. Season with salt and white pepper. Store beurre blanc in a thermos until ready to serve.
