Perfect beef fillet


Perfect beef fillet.

This beef fillet is cooked at 56.5 degrees for two hours which leaves the Center of the thick part medium rare and the ends medium for kids.

I served it with a potato and Jerusalem artichoke gratin. Slice the potatoes and artichokes thinly and cook them until almost done in a 50/50 mix of double cream and milk. Salt and pepper to taste. Pour into a pan, grate Parmesan over it and cook on the oven for 20-30 minutes on high heat until browned.
