The rhubarb comes in all at once every June — far more than one person could use, which suits me fine, since I never did learn to cook for just the one. This is where my summer starts. Let it sit a full twenty minutes before you serve it; it needs that to set, and nobody ever waits, and everybody should.
Bonnie's tip: I always make enough to walk a dish next door. A warm crumble is the surest way I know to be glad you have neighbors.
