3 egg yolks
2 tbsp. lemon juice
1/4 tsp. salt
Dash of crushed red pepper
1/2 cup of unsalted butter
You will use a blender for making this sauce.
Put the first 4 ingredients in blender jar. Melt the butter in (a microwave bowl) the microwave slowly until melted. I do 10 seconds at a time until the butter is melted.
Remove the cover of the blender, or the rubbner center part of the top. You will need to pour butter into the egg mixture. Blend on the high speed setting for just a couple of seconds. Seriously, just 2 or 3 seconds is enough.
Using the high speed pour in hot butter in a thin, steady stream. It will take about 30 seconds. You are done. Discard any residue in the bottom.
