Béarnaise SAUCE:
BRING vinegar, wine, shallots and tarragon to a boil in a small saucepan over medium high heat. Boil until most of the liquid evaporates , about 5 minutes.

OFF heat, add water then whisk in egg yolks until frothy.

GRADUALLY drizzle in butter, whisking constantly to incorporate. Sauce should be thick, but thin it with a little water if needed. If it is too thin, return it to low heat and whisk constantly until thickened.

STRAIN sauce through a medium mesh strainer into a heatproof cup. Season with lemon juice, salt, white pepper, and cayenne. Serve immediately.
