Beurre Blanc

This classic beurre blanc is a quintessential French butter sauce that brings an elegant, velvety finish to any seafood dish. Combining the sharp acidity of white wine and vinegar with the rich, luxurious depth of chilled unsalted butter, it creates a perfectly balanced emulsion. The addition of shallots provides a subtle aromatic base, while a touch of double cream ensures a stable, glossy texture that coats the back of a spoon beautifully.

As a sophisticated low-sugar option, this sauce relies on high-quality fats and acidity rather than sweeteners for its rounded flavour profile. It is the ideal accompaniment for pan-seared scallops, poached salmon or steamed seasonal asparagus. For the best results, serve it immediately to enjoy its delicate, frothy consistency at its peak.

Ingredients for Beurre Blanc

  • 60ml dry white wine

  • 60ml white-wine vinegar

  • 2 tablespoons finely chopped shallot

  • 80ml double cream

  • 1/4 teaspoons salt

  • 1/8 teaspoons white pepper, or to taste

  • 2 sticks (230g ) unsalted butter, cut into tablespoon-size pieces and chilled

How to make Beurre Blanc

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.
