One pan meals. A lamb thing.
It's cooked on a tray, in the oven. He's also used a pestle and mortar.
Then he twonked the lamb joint on the oven shelf so that all the fat dripped through, on to the tray below.
Then he splatted all that on to a wooden board, and used another pot for the juices.
Ladies and gentlemen more ladies, I present to you, The Man Who Doesn't Wash Up.
