I know that there are various versions of this recipe, this is the only I have tried since seeing it on Christine Cushing Live on the Food Network Canada. It is courtesy Tony de Luca, Hillebrand Estates Winery Restaurant, Niagara on the Lake, Ontario. Although it takes some time to cook, it's incredibly easy. I've made it for guests and everyone raves about it and the garlic is sweet and amazing. I have also made it with and without the sealing dough, it's a bit messy and if you don't want to bother just make sure you seal your dish well, I used foil between the dish and lid. But I think making the dough helps keep it moist. Enjoy!
