1/2 cup butter
3 egg yolks
1 Tbsp. lemon juice
Dash of cayenne pepper

Place egg yolks in blender with the lemon juice, turn blender on high speed for 5 seconds to blend. Melt butter in microwave until almost boiling. Turn blender back on high speed and gradually pour in butter. It will thicken into a beautiful yellow hollandaise in 20-40 seconds. The sauce may be kept warm by placing the blender bowl in warm water. The sauce cannot be reheated.
