For the Pie Dough:
1 1/4 c. unbleached all purpose flour
1/2 tsp. salt
1 tsp. sugar
1/2 cup cold, unsalted butter, cut into small pieces
2 Tbl. Ice water (more if needed)
In a food processor (or by hand), pulse the flour, salt and sugar to combine. Add the pieces of cold butter, pulsing until it resembles course meal.
Add 2 Tbl. ice water and pulse until the dough is crumbly but holds together. If needed, add more ice water, 1 Tbl. at a time. Be careful not to add too much! Give the dough time to come together before you decide if you need more water. Do not overmix. It's important that little butter bits remain~ that's what gives you a flaky crust.
Turn the dough out onto a floured surface, and bring it together into a ball. Flatten it into a disc, and wrap it tightly in plastic. Then, you can continue to flatten it into a thin disc. Refrigerate at least 1 hour. (Or, in a pinch, stick it in the freezer for 20 minutes.)
Of course, you could also use a store bought pie dough.
For the Blue-barb filling:
5 cups Rhubarb, ends trimmed, cut into 3/4" pieces
1 cup Blueberries, rinsed and dried
1 cup sugar
2 1/2 Tbl. cornstarch
Pinch of salt
Mix ingredients together in a bowl. Set aside while you make crumb topping.
For the topping:
In a medium bowl, combine 3/4 cup unbleached all purpose flour, 1/3 cup packed brown sugar, 3 Tbl. sugar, and a pinch of salt. With your fingers, or a pastry blender, work in 6 Tbl. of cold unsalted butter until large clumps form.
Chill until ready to use.
Now it's time to assemble!! One step closer to sinking your teeth into something truly glorious!
Take your dough out of fridge and plastic. Using your knuckles, make dimples around the edge. This helps the dough not to crack around the edges. Roll out the dough on a well floured surface, into a 14" circle.
Carefully transfer to a greased, 9" pie plate.
Fold leftover dough back on intself to create a thick crust. No sense in letting any of it go to waste!
Then, crimp with a fork or your fingers. Whatever floats your boat.
Pour in your fruit filling. Sprinkle crumble on top. And slip into an oven, preheated to 375 degrees.
Bake about 1 hour, or until bubbly and crust is golden brown. If it starts to darken to early, tent with foil for a while.
Cool at least 45 minutes. Unless you're like me and can't wait that long. In which case, the pie will still taste just as good, but be a bit more runny.
