This polenta is actually a polenta, ham, tomato and cheese gratin. A very tasty dish for the cooler times of the year.
This recipe uses a couple of ingredients you may not readily find but can easily find substitutes for.
The first one of these is “Bramata Polenta” which can be replaced by any brand of coarse ground corn meal or “grits”.
The other one is “Raclette” cheese. This can be substituted with (in order of my preference): Jarlsberg, Emmentaler (aka Swiss Cheese) or then Gruyere. If you’re really stuck, use “Mozz”.
