Rhubarb Crumble

Step 1

Prepare the filling: Toss the rhubarb cubes with sugar and flour. Set aside and let macerate while you make the topping, about 20 minutes.

Step 2

Make the topping: Put flour, sugar, baking powder, salt, ginger and cinnamon in a bowl, and stir together. Add butter and work into flour with fingers or a fork, as if making pie dough. The mixture will be loose and crumbly. Stir in the pistachios, if using.

Step 3

Heat oven to 375 degrees. Transfer sugared rhubarb to a 9-inch baking dish, about 3 inches deep. Sprinkle topping loosely over fruit to a depth of about 1 inch.

Step 4

Place dish on a baking sheet and bake for about 1 hour, until topping is golden and filling is visibly bubbling at the edges. Cool slightly before serving.
