Add the egg yolks, lemon juice and 1 tablespoon scalding hot water to the jar of a blender or bowl of a food processor and pulse to combine.

With the machine continuously running, slowly pour in the butter infused olive oil, a little at a time.

Continue blending, adding the remaining olive oil in a thin stream until the mixture emulsifies.

Adjust seasoning with additional salt and/or pepper and serve immediately.
