Step 1
First, I crack the egg yolks into the blender, add the mustard, lemon juice, and a dash of hot sauce. Blend for just 5 seconds—no more than that. While the eggs are blending, I melt the butter in a microwave-safe cup until it’s piping hot and fully melted. Then, with the blender running on high, I slowly drizzle the hot butter in a steady stream through the opening. It’s like magic: the sauce thickens immediately into a creamy, airy emulsion. If it gets too thick, a teaspoon of warm water can loosen it up. To keep the sauce warm, simply set the blender container in a pan of warm tap water until serving time. This method never fails me.
