It’s a traditional British crumble featuring soft-cooked rhubarb, flavored with stem ginger in syrup, and topped with a coarse, crunchy crumble mixture made from flour, butter, and sugar. James Martin keeps the recipe simple but full of texture and taste, often serving it with clotted cream or custard.
