When my father was a kid growing up in Minnesota, in the summer he used to love to chew on rhubarb that grew like a weed around there, RAW.

That's right. Raw. (The stalks, not the leaves which are poisonous.)

Have you ever tried biting into a piece of raw rhubarb stalk? I dare you. It's like a hundred times more sour than a lemon (okay maybe a little exaggeration here). It's screaming tart. It's "what was I thinking?" tart.

Anyway, rhubarb is not safe around this house. The refrigerator half life for rhubarb is a couple hours at best. This last bunch we put to work into this lovely rhubarb crumble!

Taking a tip from The Flavor Bible, I added a touch of cardamom to the vanilla and rhubarb in the filling, rhubarb+cardamom+vanilla being one of those match-made-in-heaven flavor combinations.

Another favorite combo with rhubarb that I love is ginger and orange zest, which would also work great with this crumble. Feel free to experiment.

The only thing you need to really keep an eye on is making sure you have enough sugar to balance out the tartness of the rhubarb.

The ratio of rhubarb to sugar in this recipe is perfect for us, but if it ends up being too tart for you, add a little more sugar, or just eat with vanilla ice cream, whipped cream, or even straight cream.

  3. Make topping:

    In a food processor, pulse together 1 cup of flour, the salt, and the brown sugar. Add the butter and pulse until the pieces of butter are pea-sized. (Alternatively, mix the dry ingredients together and cut the butter in with two knives or a pastry cutter.)
