I've never attempted this again! Many years ago, I had sheep's brains in a Turkish restaurant, which I enjoyed very much. I thought I'd replicate the dish, so I visited my butcher who didn't have any brains. However the spring lambs were due in in a couple of weeks and he said he'd keep a couple of heads for me. I collected them and returned home by bus with a carrier bag in each hand, each containing a lamb's head. Have you any idea how difficult it is to open up a lamb's head with ordinary household & kitchen tools? Several hours later I'd used a selection of saws, pliers, cold chisels & knives and I'd got the brains out. Blood spots & bone splinters were found in the kitchen for several weeks thereafter. Nevertheless, I braised the brains, sliced them into a dish, covered with fresh tomato sauce, topped with potato gnocchi, sprinkled with cheese and baked them. I thought they were delicious. My wife hated them!
