Bluebarb equals rhubarb plus blueberries and it is quite possibly my favorite pie. Apple is also high on the list, and pumpkin…I just really like pie. And what better way to use the fruits of summer?

A Little Bit About Rhubarb

The sour, stalky rhubarb is actually a vegetable, though I have never heard of a savory recipe using rhubarb that doesn’t make my lips pucker. Reading more about the plant, I was hopping to discover it as a secret nutrition powerhouse, but it only offers a meager amount of vitamins C and A. The addition of  blueberries to the ‘barb boosts both the antioxidant and vitamin C concentration in the pie.

However rhubarb is not totally worthless (besides being delicious of course).  The ancient Chinese commonly used rhubarb to induce vomiting. Centuries later, in Europe during the fifteen and sixteen hundreds rhubarb in dried form sold for similar medicinal purposes for ten times the price of cinnamon and double that of opium. And I only pay a dollar for it at the farmers market. Lucky me!

Yesterday Marshal brought me a bundle of rhubarb from the farmers market and asked very nicely if I would make him a pie. He also brought sunflowers and a dashing smile, just to sweeten the deal. I happily complied.

Bluebarb Pie (Recipe adapted from Cooks Illustrated)

2 1/2 cups all purpose flour
1/2 cup fine or medium ground cornmeal
1 teaspoon salt
2 tablespoons salt
7 tablespoons crisco cut into pieces (I know, I know, but its great)
11 tablespoons cold butter cut into pieces
10 tablespoons ice water

2 teaspoons vegetable oil
1 or 2 bunches rhubarb (1-2 lbs) edges trimmed of gross bits, cut into 1- inch size pieces (5-6 cups)
1 pint blueberries
3/4 cup sugar plus a bit for dusting the top crust
3 tablespoons arrowroot ( a white powder found in the spice section)
Pinch o salt
1/2 teaspoon vanilla extract
1 egg white, beaten

Grab a nine inch pie pan and set the oven to 500 (scary, but the temp comes down right away)

1. This dough is very versatile. Keep some in the freezer for a spur-of-the-moment tart, crostata or pie . The addition of the cornmeal adds a welcome counterpoint texture to the smooth fruity insides. Pulse dry ingredients in the bowl of a food processor, till mixed. Add crisco and pulse until flour mixture looks like sand that’s about ready to make a castle, or about 5 seconds. Next add butter and blend with 12 1-second pulses.  The butter should be cut into the flour in blobs no bigger than small peas. Dump dough into large mixing bowl and sprinkle ice water over top. Press dough together with a spatula or your hands until it forms a ball. Divide dough into two parts, flatten each into 6 inch discs and refrigerate.

2. Heat the oil in a large sauce pan until very hot, then toss in rhubarb. Get ready! It’s going to sizzle and smoke! Add 1/4 cup of the sugar and cook until rhubarb has released most of its liquid but is still firm, roughly five minutes. Set in the fridge to cool.

3. Its time to roll out the dough! Take one of the discs out of the fridge and flour your work surface.  Now proceed to roll it out, adding as much flour as you go. It helps to rotate and turn the dough over as you work, that way it will be easier to plop in the pan.  Roll until dough is a fourth of an inch thick then place it in the pan, and put the pan in the fridge to keep the dough chilled.

4. Combine remaining sugar (plus more if you want a sweeter inside), arrowroot and salt in a small bowl. Now go fetch the cooled rhubarb and combine with blueberries in a large mixing bowl. Sprinkle sugar mixture over the fruit and gently mix, then pop the whole mess into the pie pan.

5. Proceed to roll out the other piece of dough. Gently slide it over the pie and trim off excess around the  edge, leaving enough to make a tasty crust. Now roll edge dough under and press with a fork to seal. Create 8 slices in the top to allow steam to escape.  Brush pie with beaten egg white and sprinkle with remaining tablespoon of sugar.

6.  If you’re afraid there is just too much goodness inside, place pie on a cookie sheet to catch any spills. Now its time to get this bad boy in the oven. Immediately lower the temperature to 475 and bake for 25 minutes, until crust is lightly golden. Then lower temperature again to 375 and continue to cook until fruit bubbles through the slits.

7. Wait as long as you possibly can to eat it. Shoot for a few hours. Seriously, its better when it doesn’t scald you. Oh, lastly, make sure you have good vanilla ice cream on hand!  Happy eating!
