Place the tomatoes in an oven-proof dish, season with salt and pepper, scatter your garlic, and then, in a generous fashion, splash your olive oil over all. Put into a hot oven for approximately 25 minutes until the tomatoes are soft and giving. Remove from the oven and check that the garlic is soft and cooked; if not, remove the tomatoes onto a plate and pop the garlic back into the oven until cooked. Once ready return the tomatoes to the dish. Nestle in your crottins and return to the oven until they are giving but not gone. Once again, remove from the oven.
