1. Put the egg yolks, lemon juice and salt into the mixing cup. Slowly
pour the warm butter into the cup, carefully leaving any white milk
solids on the bottom of the pot behind. Allow to rest for about
1 minute.
2. Insert the blending shaft into the cup so that the blade guard touches
the bottom of the cup. Blend on Low, keeping the blade on the bottom. Once the ingredients thicken and start to emulsify, continue
processing, using a gentle up-and-down motion, until thick and all
the ingredients are incorporated.
3. If sauce is too thick, blend in warm water, 1 teaspoon at a time, until
desired consistency is achieved (approximately 2 tablespoons total).
4. Taste and adjust seasoning as desired. Serve immediately or transfer
to a double boiler to keep warm.
