Bring the chicken stock with about 20 grams of butter to the boil, slowly stir in the corn grits, add a little salt and pepper and simmer gently for about 20 minutes until it is nice and firm. Then spread the mixture as thick as a finger on a baking sheet brushed with olive oil and let it cool, cut into sections for the gratin dish.
For the tomato sauce, melt 20 grams of butter in a pan, sauté the onions and garlic, add the tomato paste and immediately deglaze with a dash of red wine and immediately add the tomatoes from the can with the liquid. Add the bay leaves and let the sauce reduce slightly over a medium heat for about 15-20 minutes until it becomes a bit thick.
Season the sauce well with salt and pepper and remove the bay leaves.
Preheat the oven to 180-200 degrees.
Brush a tall, fireproof dish with a little olive oil. Layer alternately a layer of polenta, tomato sauce, parmesan and butter flakes. Finish with tomato sauce, parmesan and butter flakes.
Then bake the whole thing in the oven at 180-200 degrees for about 30 minutes.
Tip:
If you like, you can refine the tomato sauce with herbs such as thyme, marjoram, sage and basil. Or an Italian herbal mixture.
