It was very tasty, but not hard:
Reverse sear on the steak no mystery there.
The crab comes out of a can, heat for a minute 45 sec in a glass dish in the microwave. The recipe call for Jumbo Lump but I could only find claw meat here locally.
Hollandaise, Three egg yokes and 1 tablespoon lemon juice in a blender beat for 5 seconds. Microwave 1 stick of butter in a large measuring cup until boiling. Slowly pour the melted butter into the running blender, sauce will immediately thicken, blend for a few seconds more. I poured the sauce into a squeeze bottle. put the bottle in a large thermal mug. Fill mug with HOT water.
Put a ring mold on the steak to hold the crab until ready to sauce it.
