Pop it in a 180°C oven, and by the time you're out of the shower, a beautifully colored cauliflower gratin awaits. *The night before, I boiled the cauliflower, melted butter with a little flour, and made the cream sauce with milk, heavy cream, salt, and pepper. Just ten minutes of effort before bed is all it takes.
