Yes that is a lamb's brainEating 'cervello' or the brain of lamb was another first in Florence, my father would be proud of me. It tasted like a mix between a hard boiled egg and mashed potatoes with a chalky after taste.
It wasn't bad at all - just a bit scary to take the first bite. It's texture was the most interesting /unusual part. Since it was served in one of the best restaurants in Florence I knew it would be cooked well, which it was. It was seasoned with olive oil and garlic and baked in the oven in this little foil envelope.
Thanks to the wonderful staff and chef at Cibreo for our wonderful meal.
