Ingredients:
- 2 tbsp unsalted butter
- 2 tbsp shallots, minced finely
- 1/2 cup white grape juice
- 1 tbsp lemon juice
- 12 oz unsalted butter, chilled and cut into 1/2 inch cubes
- 2 tbsp heavy cream
- 1/2 tsp kosher salt
- 1/4 tsp white pepper
Instructions:
- Melt 2 tablespoons of butter in a small saucepan over medium-low heat.
- Add the minced shallots and sauté for 2–3 minutes until translucent and fragrant, but not browned.
- Pour in the white grape juice and lemon juice. Increase heat to medium and simmer until the liquid is reduced to a syrupy consistency, with roughly 2 tablespoons of liquid remaining.
- Stir in the heavy cream and simmer for another 1–2 minutes until the cream has thickened slightly and is fully integrated.
- Turn the heat down to the lowest setting.
- Add 2 cubes of chilled butter and whisk constantly until melted.
- Continue adding the remaining cold butter 2 cubes at a time, whisking vigorously and continuously until the sauce is opaque and creamy.
- If the sauce looks too hot or oily, lift the pan off the heat for 10 seconds while continuing to whisk, then return it to the burner.
- Stir in the kosher salt and white pepper.
- Place a fine-mesh strainer over a warm bowl and pour the sauce through the strainer to remove the shallots.
