Rhubarb Crumble with Ginger

February is a lean month. The garden is asleep, the market is a parade of root vegetables and stored apples, and most evenings end with the same question: what, honestly, is for pudding. And then the forced rhubarb arrives, impossible pink stalks grown in the dark of Yorkshire sheds, and suddenly the cold months have a point.

This is the pudding I make more than any other between January and March. Rhubarb, sugar, ginger, and a proper crumble on top. Nothing clever. The ginger matters, though. Rhubarb and ginger belong together the way apples belong with cinnamon. One sharpens the other, and the warmth of the ginger answers the sourness of the fruit like they were waiting to meet. If you've got a jar of stem ginger in the cupboard, a chopped piece and a spoonful of its syrup lift the whole thing. If you haven't, ground ginger alone does the job perfectly well.

The crumble itself is the usual business. Flour, butter, sugar, a handful of oats for texture, rubbed together until it looks like rough breadcrumbs with a few larger pebbles still holding on. Those big lumps are the ones you want. They go dark and craggy at the edges, almost toffee-ish, and they're what separates a crumble worth making from one you won't remember.

I wrote it down in the notebook years ago: "Rhubarb. Ginger. Friday. Rain." It's the whole recipe, really. Everything else is just the how.
