Set out a large high-powered food processor. Make sure to trim all the silver skin and fat off the fillet and cut the fillet into large chunks. Place in the food processor.
Add the cayenne, salt, anchovy paste, garlic powder, and cardamom. Pulse to chop the fillet into fine chunks. You can choose to stop when the beef resembles ¼ inch chunks or chop smaller into ground steak.
Once the texture is to your liking, melt the clarified butter and pour over the top. Mix the butter in by hand, do not pulse.
Serve raw immediately, cover and chill, or pan-fry over high heat for 1 to 2 minutes.
