Beurre Blanc
A foundational French butter sauce
Ingredients
- 1 small shallot finely minced
- ½ cup dry white wine
- 1-2 teaspoons lemon juice or white wine vinegar
- 8 tablespoons unsalted butter (1 stick) cold and cut into pieces
Optional
- 1 tablespoon cream for stabilization, not traditional but useful
Instructions
Build the reduction
- In a small saucepan, combine the shallots, wine, and vinegar.Bring to a simmer and reduce until the liquid is nearly gone, with just a few tablespoons remaining. The pan should look almost dry, but not browned.This reduction is the backbone of the sauce. It should be concentrated and slightly sharp.
Lower the heat
- Remove the pan from direct heat or reduce to very low.This is the moment where most beurre blanc fails. If the pan is too hot, the emulsion will break before it forms.
Mount the butter
- Add the butter one cube at a time, whisking continuously.Allow each piece to melt and incorporate before adding the next. Move the pan on and off the heat as needed to keep the temperature controlled.As the butter incorporates, the sauce will become pale, slightly thickened, and glossy.
Adjust and finish
- Once all the butter is incorporated:If needed, add a small splash of warm water to loosen the texture.Strain out the shallots if you prefer a refined finish, or leave them in for a more rustic version.Season lightly with saltTaste for balance. It should be bright, not sharp
