We have prepared this recipe using buckwheat, also known as ‘taragna’. If you want to follow the traditional recipe, use simple corn polenta instead, and take care to make it very soft whilst cooking. You can then add the cubes of cheese, so as to blend them in nicely, or cover your polenta with the cheese and butter at the end and blast under a grill, like a gratin. Fortunately, flavoured polenta is not a formal or rigid recipe, so you can use your imagination by adding any cheese you like, and the method that suits.
