SPINACH AND MUSHROOM GRATIN

Steps:

• Preheat the oven to 350°F (180°C). Halve or quarter the mushrooms, depending on their size. Warm the butter and 2 tablespoons of oil in a deep pan and add the mushrooms, letting them color nicely here and there (expect to add more oil if they drink it all). Pour in the wine and bring to a boil. Continue to boil for a couple of minutes.
• Pour the cream into the pan and let it come back to a boil, then simmer for two minutes. Turn off the heat. Wash the spinach and put it, still wet from rinsing, into a pan with a tight-fitting lid. Let the spinach cook for a minute or two in its own steam, then drain it and squeeze to remove excess water.
• Reserve several tablespoons of the Parmesan. Fold together the mushrooms, drained spinach, salt and black pepper, and the rest of the grated Parmesan. Put into a shallow baking dish. Scatter the reserved cheese on top and bake for thirty-five minutes, until the top is crisp and golden.
