Beurre Blanc Sauce

Ingredients

• 1 pound cold unsalted butter
• 1 cup dry white wine
• 1/2 cup white wine vinegar
• 1 tablespoon finely chopped shallot
• Kosher salt, to taste
• Steps to Make It
• Gather the ingredients.
• Cut the butter into medium (1/2-inch) cubes and return them to the refrigerator to keep them cold.
• Heat the wine, vinegar, and shallot in a saucepan over high heat until the liquid boils. Continue boiling until the liquid has reduced down to about 2 tablespoons, about 30 to 40 minutes.
• Reduce the heat to low, take the cubes of butter out of the fridge and start rapidly whisking them in, 1 or 2 at a time, to the reduction. As the butter melts and incorporates, add more and keep whisking. Continue until you only have 2 to 3 cubes remaining. This process should take about 25 to 30 minutes.
• Remove from the heat while whisking in the last few cubes, and whisk for a moment or two more. The finished sauce should be thick and smooth.​
• Season to taste with kosher salt.
• Traditionally, the chopped shallot would be strained out before serving but doing so is optional. Serve right away. Enjoy.
