For Hollandaise sauce
Melt the butter slowly in a small pot. Try not to let it boil – you want the moisture in the butter to remain there and not steam away.
Add the egg yolks, lemon juice, salt, Dijon, and cayenne (optional) into a bowl. Blend the egg yolk mixture at a medium speed with an immersion blender (or use a traditional bender or a whisk) until it lightens in color, about 20-30 seconds.
Once the yolks have lightened in color, turn the blender down to its lowest setting and drizzle in the melted butter slowly, while the blender is going until it is a smooth sauce. *You can also use a whisk and stir constantly over a double boiler.
Can be made the night before, refrigerated, and reheated the next morning.
