- 3 large egg yolks
- 1 tsp fresh squeeze lemon juice
- 1/2 tsp salt
- 1/8 tsp cayenne pepper
- 1/4 tsp mustard powder
- 8 tbsp unsalted butter
In your blender, combine egg yolks, lemon juice, salt, pepper, and mustard. Blend on high speed to combine, about 20 seconds.
Heat your butter either on stovetop or microwave until completely melted and hot. This next step is very important. Put your blender on low speed, and slowly pour in the hot butter a little at a time. Do not pour in too fast, otherwise your sauce will not come together. The sauce should start to come together as you slowly pour in the butter, turning a pale yellow and thickening. Continue to blend for a few seconds after all the butter is incorporated. Taste the sauce. If you want, you can adjust the lemon, cayenne, etc. Serve sauce while still warm.
