Ingredients:
- 1/4 cup (60ml) dry white wine
- 1/4 cup (60ml) white wine vinegar
- 1 tablespoon (15ml) finely minced shallots (about 1 medium)
- 1 teaspoon (5ml) coarsely cracked black peppercorns
- 1 bay leaf (optional)
- 3 large egg yolks
- 1 tablespoon (15ml) water
- Pinch of cayenne pepper (optional)
- 1/2 cup (113g) unsalted butter, clarified or melted and cooled slightly
- 1 tablespoon (15ml) finely chopped fresh tarragon
- 1 teaspoon (5ml) finely chopped fresh parsley
- Salt and freshly ground white pepper to taste
Instructions:
- Prepare the Peppercorn Reduction: Combine wine, vinegar, shallots, peppercorns, and bay leaf (if using) in a small saucepan. Simmer over medium heat until reduced to about 2 tablespoons of liquid. Strain through a fine-mesh sieve (optional).
- Prepare a Bain-Marie (Double Boiler): Place the heat-resistant bowl over a saucepan of simmering (not boiling!) water. Make sure the bottom of the bowl doesn't touch the water.
- Emulsify the Yolks: In the bowl, whisk together the egg yolks, water, cayenne pepper (if using), and strained peppercorn reduction. Whisk constantly until the mixture becomes pale, thick, and foamy.
- Slowly Incorporate the Butter: Remove the bowl from the heat and very gradually drizzle in the clarified or melted butter, whisking constantly and vigorously. Start with a few drops at a time, then increase the flow as the emulsion forms.
- Finish the Sauce: Stir in the chopped tarragon and parsley. Season with salt and white pepper to taste.
- Serve Immediately: Béarnaise is best served immediately. If necessary, you can keep it warm in a thermos or over a very low heat bath (bain-marie) for a short time, but be careful not to overheat it.
