Ingredients

Ingredients:

4 egg yolks

2 Tbs. fresh lemon and lime juice

1 Tbs. water

1/8 tsp. salt

Pinch of cayenne pepper

2 pinches of freshly ground white pepper

16 Tbs. (2 sticks) unsalted butter, melted

Preparation

Directions: In a heatproof bowl set over a saucepan of barely simmering water, combine the egg yolks, lemon and lime juice and water and whisk constantly until the mixture begins to thicken, then continue whisking about 1 minute more. Remove the bowl from over the pan as soon as the mixture thickens. Add the salt, cayenne pepper and white pepper.

Using a stick blender with the aerator attachment, blend the mixture while slowly pouring in the melted butter in a thin stream until incorporated, about 2 minutes. Taste and adjust the seasonings. Cover and keep warm over very low heat, or transfer to a cast-iron sauce warmer until ready to serve. Makes 2 cups.
