Creamed Savoy Cabbage Gratin

January. The garden is bare and the market stalls are half what they were in September. But there's a Savoy cabbage, heavy and cool in the hand, its crinkled leaves still frosted at the edges. This is its moment. A cabbage that has been through a frost tastes sweeter than one that hasn't, and a Savoy takes to cream the way few other vegetables do.

A gratin is a generous way to cook it. You blanch the cabbage briefly, fold it through a simple cream sauce sharpened with nutmeg, and bake the whole thing under breadcrumbs until the top goes golden and the cream bubbles up at the edges. The kitchen fills with that particular smell of butter and toasting bread and warming cream that makes people wander in and ask what's for dinner.

I wrote this down in the notebook years ago, the first time I made it as a side for a roast chicken on a Sunday when the wind was rattling the window. The note said: cabbage gratin, nutmeg, good. That was enough. It's a dish that doesn't ask for much, a decent cabbage, real cream, some attention, and gives back more than it should. There are few better feelings than putting a warm plate in front of someone on a cold evening and watching them go back for a second spoonful without being asked.

A recipe is a conversation, not a contract. If you want to add a layer of leeks, do. If you prefer Gruyère to Parmesan, use it. Your kitchen, your rules.
