Julia Childs Beurre Blanc White Butter Sauce Recipe On Food52

Steps:

• In a 1 1/2 quart saucepan combine vinegar, wine, shallots, salt and white pepper and bring to a simmer.
• Gently simmer liquid until reduced to 1 1/2 tablespoons. Remove from heat and immediately swirl or whisk in 2 pieces of chilled butter. As the butter is incorporated into the liquid add another piece and continue to swirl or whisk. Return pan to low heat and while constantly swirling or whisking add successive pieces of butter. When all of the butter has been added remove from heat. Sauce will be thick and creamy. Adjust seasoning to taste. Serve immediately. To hold the sauce, set the pan in a larger pan of lukewarm water. If the sauce separates, transfer a spoonful of the sauce to a cold mixing bowl and gradually whisk the rest of the sauce in by the spoonful. The sauce can be reheated by gradually whisking 2 to 3 tablespoons of hot liquid, i.e. water, cream or stock.

Steps:

• In a heavy 2-quart saucepan, combine vinegar, wine, shallots, lemon, and bay leaves to make an infusion. Simmer over medium heat for 5 to 8 minutes until the mixture is reduced to a wet paste, about 2 tablespoons. Add the cream and continue to simmer until reduced again to about 2 tablespoons. Cream is added to make the sauce more stable and less likely to separate.
• Reduce the heat to low and remove the bay leaves. Whisk in the chunks of butter in small batches. The butter should melt without the sauce getting too hot, producing a creamy emulsified sauce. Do not let the sauce go over 130 degrees F, where it will separate. If the sauce starts to break, remove from heat, add 2 ice cubes and whisk until it cools down and comes back together. Season with salt and pepper, fold in the chives, and serve immediately. Keep covered in a warm place for a few hours, if needed.
• Serve with fish or vegetables.
