Ingredients
3 egg yolks
1 tablespoon lemon juice
¼ teaspoon Dijon mustard
1 dash hot pepper sauce (e.g. Tabasco)
½ cup butter
Directions
Combine egg yolks, lemon juice, mustard, and hot pepper sauce in the container of a blender; cover and blend for about 5 seconds.
Place butter in a glass measuring cup. Heat butter in the microwave for about 1 minute, or until hot and completely melted.
Turn the blender on; pour melted butter in a slow, steady stream until sauce is thick and smooth, about 15 to 30 seconds.
