Simple Butter Sauce

Ingredients

• 6 tablespoons Butter, unsalted (Divided into three portions of 2 tablespoons each)
• 2 Egg yolks (Large eggs)
• 1 tablespoon Lemon juice, fresh
• 0.333 cup Boiling water
• 0.125 teaspoon Salt (Or to taste)
• 0.0625 teaspoon Cayenne pepper (Pinch, or to taste)

Instructions

1. 1Place the butter in a bowl, cover with cold water, and wash, using a spoon. This helps remove excess milk solids. Drain the water.
2. 2Divide the butter into three equal pieces (approximately 2 tablespoons each).
3. 3Put one piece of butter in a heatproof saucepan with the egg yolks and lemon juice. Place the saucepan in a larger saucepan containing simmering water (double boiler). Stir constantly with a wire whisk until the butter is melted and the mixture starts to thicken (about 3 minutes). Add the second piece of butter, and continue stirring until thickened. Add the third piece of butter and continue stirring until the sauce is smooth and emulsified.
4. 4Add the boiling water, cook for one minute, stirring constantly. Season with salt and cayenne pepper to taste.
