A modern twist on the classic Béarnaise, this version incorporates sorrel for a bright, lemony depth. Spoon it over steak, fish, or chicken for extra richness.

Method
Make Vinegar Reduction: Combine chopped shallot, half of the sorrel, white pepper, and vinegar in a small sauté pan. Simmer over low heat until reduced by 80%. Strain and set aside.
Set Up Double Boiler: Fill a saucepan with 2 inches of water. Bring to a gentle simmer. You're looking for a bare simmer: small bubbles breaking the surface, not a rolling boil.
Start the Sauce: In a metal bowl, whisk together egg yolks, water, and lemon juice.
Cook the Eggs: Place the bowl over the saucepan (make sure it doesn’t touch the water) and whisk constantly for 2 minutes until thickened slightly.
Add Butter: Whisk in butter one cube at a time, ensuring each piece melts and emulsifies before adding the next.
Finish the Sauce: Remove from heat. Stir in the vinegar reduction, chopped fresh sorrel, a pinch of salt, and a dash of hot sauce if desired.
Notes
Storage: best made and served the same day; the emulsion breaks on reheating. If needed, hold at room temperature, not chilled, for up to 2 hours.
