Gremolata Hollandaise Sauce
Heat the butter and olive oil in a small sauce pan until very warm, about 180 degrees.
In the bowl of a food processor or in the jar of a blender, add the vinegar, lemon juice, salt, pepper, and egg yolks.
Process briefly to blend everything.
With the motor running, slowly drizzle in warmed olive oil and butter.
