Though I only looked at it once after eating it at Trullo, it’s not exactly difficult to cook and now I just use what’s to hand rather than follow a recipe, I use ox cheek, venison or whatever braising is available and cook it for a long time sometimes starting in the morning and leaving the oven to cool and then back on a couple of hours before eating, the longer cooking the better.
