Ingredients
Instructions
Combine the finely minced shallots, white wine, and white wine vinegar in a small saucepan over medium-high heat.
Simmer the liquid until it has reduced by about two-thirds, until only 1-2 tablespoons of liquid remain (this is called 'au sec').
If using, stir in the tablespoon of heavy cream and reduce for an additional 30 seconds to thicken slightly.
Reduce the heat to the lowest setting. Add the first cube of cold butter and whisk vigorously until melted.
Continue adding the butter cubes one or two at a time, whisking constantly to create a smooth, creamy emulsion.
Control the temperature by moving the pan on and off the heat; the butter should melt slowly and not turn into oil.
Once all the butter is incorporated, the sauce should be thick and opaque.
Season with a pinch of salt and white pepper to taste.
Strain the sauce through a fine-mesh sieve if you prefer a completely smooth texture, discarding the shallots.
Serve immediately while warm.
💡 Chef's Tip
Maintain a low temperature throughout the butter incorporation phase; if the pan gets too hot, the butter will melt into oil rather than emulsifying. If the sauce begins to separate, remove it from the heat immediately and whisk in a teaspoon of ice-cold water or heavy cream to bring it back together.
