Strawberry Rhubarb Crème Fraîche Crumble Pie

I wish I could say that I made this pie especially for Pi Day (3/14, get it?), but the truth is that I only realized my lucky coincidence when Jay spotted a sign in Green Chili Kitchen advertising a slice of their green chili apple pie for $3.14 today.

The truth is, I’ve been dying to bake a pie lately. I mostly think about it during yoga class, (which probably isn’t what the teacher means when she tells us to set an intention, but oh well). I try to shift my focus back to my practice and be present with my burning quadriceps, aware of the discomfort of being twisted into a pretzel, and focused on my inhalations and exhalations (usually more of a shallow panting).

This often goes something like this:
I’m letting go of thinking about pie. Yes, in fact I’m cutting it out of my brain. Slicing it cleanly out of my head. Like cutting a wedge out of a warm, gooey pie. Inhale, exhale. A shaker lemon pie, infused with blood orange and vanilla bean. Or maybe a chocolate stout pecan pie. Or a strawberry rhubarb pie enriched with crème fraîche and flecked with vanilla bean seeds and meyer lemon zest… No, stop. Yoga. Breathing. Oh god I’m so hungry…

pie…

As though divined by Shiva, a pound of slender, ruby stalks of rhubarb showed up in my kitchen via Jay’s mom’s garden. (Thank you, Mary!!!) And the first local strawberries appeared at our co-op the next day.

I based the recipe on this Nectarine Crème Fraîche Pie that I made last year, which I adapted from Deb who adapted it from Martha. I increased the streusel and crème fraîche, traded strawberries and rhubarb for the nectarines, and added cardamom, brown sugar and oats to the topping to make it more crisp-like. A super-flaky par-baked crust gets spread with some of the crème fraîche and topped with a bit of streusel. The streusel base soaks up some of the juices from the fruit, which gets tossed in lemony vanilla sugar and loaded on top. More crème fraîche gets dolloped over the top, and the crumble gets sprinkled over.

This pie bakes for an hour and a half, until the crumble is golden and the fruit bubbles up, its magenta juices popping through the streusel. (Bubbling fruit means that the filling is boiling, and ensures that the fruit will be firm and set rather than watery, like making jam.) A shield of aluminum foil prevents the crust from burning.

The result is a meltingly tender center bursting with the sweet-tart flavor of strawberries and rhubarb, all coated in a nap of vanilla bean-flecked crème fraîche. The cardamom-kissed crumble and flaky crust make crisp foils for the tender filling. I usually like pie with a scoop of ice cream or whipped cream, but the crème fraîche in the filling makes this pie stand on its own.

Hopefully, now that I’ve appeased the pie gods, I’ll be better able to focus. I’m gonna need to do a lot of yoga after eating all that pie.

Happy pi day.

Author: The Bojon Gourmet

Ingredients

Flakiest, all-butter pie crust:

• 3/4 cup all-purpose flour
• 1/2 cup whole spelt (or whole wheat pastry)flour
• 1/2 teaspoon fine sea salt
• 4 ounces cold, unsalted butter, in 1/2" dice (8 tablespoons/1 stick)
• 2 tablespoons buttermilk or crème fraîche (or more ice water)
• 2 tablespoons ice water, more as needed

Cardamom Streusel:

• 3/4 cup all-purpose flour
• 1/2 cup powdered sugar
• 1 teaspoon ground cardamom
• 1/2 teaspoon baking powder
• 1/4 teaspoon salt
• 4 ounces unsalted butter, cold, cut into chunks (1 stick)
• 2 tablespoons brown sugar
• 1/3 cup quick oats

Strawberry Rhubarb Crème Fraîche Filling:

• 1 pound rhubarb stalks, trimmed, sliced 1" thick (4 cups)
• 1 scant pint strawberries, hulled (quartered if large, halved if medium, left whole if very small (1 1/2 cups cut)
• 1/2 cup granulated sugar
• seeds from 1/2 vanilla bean
• zest of 1/4 of a (meyer)lemon
• pinch salt
• 1 cup crème fraîche, divided use

Instructions

Make the crust:

• In a large bowl, stir together the flours, sugar and salt. Scatter the butter pieces over the flour, and rub in with your fingertips until the mixture resembles sand with lots of pea-sized butter chunks. Stir together the buttermilk and ice water. Drizzle this mixture over the flour mixture, 1 tablespoon at a time, tossing with a rubber spatula, until the dough will hold together when you give it a squeeze, adding more ice water by the teaspoon directly to the dry bits as needed.

You can call it here, or you can do either or both of the steps below for extra flake:

Option 1 - fraisage:

• Dump the dough out onto a counter, divide it roughly into 8 portions, and fraisage by dragging a portion of dough across the counter using the heel of your hand. Scrape up the dough (a metal bench scraper works well here), gently press it into a ball and flatten into a disc. Slip it into a plastic bag, and chill for at least 30 minutes or up to 2 days.

Option 2 - roll, fold, roll:

• On a lightly floured surface, roll the chilled dough out into a rough square that is about 1/4" thick. Fold it in thirds like you're folding a letter, then roll up from a skinny end into a loose spiral. Gently press to flatten it slightly, and chill for 30 minutes to 1 hour.
• Remove the dough from the fridge, unwrap, and place on a lightly floured surface. Roll out the dough into a 12" circle, dusting the dough lightly with flour as needed, rotating and flipping it to prevent it from sticking. Ease the dough into a 9" glass pie plate, fit it into the corners, and trim it to a 1" overhang. Fold the overhang under, and flute the crust by pressing it between the thumb of one hand and the index finger and thumb of the other hand. Prick the dough all over with a fork.
• Chill the crust for 20 minutes, then freeze it for at least 20 minutes, until solid.
• Position a rack in the lower third of the oven and preheat to 400º.
• Place the frozen crust on a rimmed baking sheet. Line it with a piece of parchment paper or foil, and fill with pie weights, dry beans, or clean pennies, pressing the weights into the sides and corners of the crust.
• Bake the crust for 15-20 minutes, until the dough will hold its shape when you lift off the parchment, then remove the weights and parchment and bake until the bottom is dry and lightly golden, about 5 minutes longer. Reduce the oven temperature to 375ºCool the crust slightly.

While the crust bakes, make the streusel:

• In a medium bowl, combine the powdered sugar, baking powder, salt and flour. Add the butter cubes, and work with your fingers or a pastry blender until it begins to clump together. Set aside. (You'll use the brown sugar and oats later.)

While the crust cools, make the filling:

• In a large bowl, rub the vanilla bean seeds, lemon zest and salt into the sugar until combined. Toss in the rhubarb and strawberries to coat.

Assemble the pie:

• Spread 1/4 cup of thecrème fraîche in the bottom of the cooled pie crust. Sprinkle 1/2 cup of the streusel over thecrème fraîche. Mix the brown sugar and oats into the remaining streusel. Pour the strawberries and rhubarb into the pie and top with any extra juices. Dollop the remaining 3/4 cup crème fraîche over the fruit, then sprinkle evenly with the remaining streusel.

Bake the pie:

• Criss-cross two long pieces of foil on a baking sheet, set the assembled pie in the middle, then fold the foil up and over the crust, scrunching as necessary so that the foil just covers the crust and leaves the filling exposed. Bake the pie until the streusel is golden all over and the fruit is bubbling, about 90 minutes. Rotate the pie halfway through for even baking. Let cool at least 1 hour, then serve warm or at room temperature.
• The pie is best the day it has been baked, but will keep for 24 hours at cool room temperature, or up to a few days in the fridge.

Notes

Adapted from this Nectarine Crème Fraîche Pie which was adapted from Deb who adapted it from Martha.

I like this pie best shortly after being baked, but I've been known to swipe slices straight from the fridge on days 2 and 3. The crust can be par-baked in advance and stored for a few days in the fridge, and the streusel can be made a day ahead and stored at room temperature.

You may wish to make a double batch of pie dough, especially if you do the fraisage and folding options described below for extra flake, and save half of it in the freezer for a future pie. For step-by-step photos for making super flaky, all-butter, semi-whole-grain pie dough, check out my pie dough tutorial.

You can make your own crème fraîche by stirring 1 tablespoon buttermilk into 1 cup of heavy cream. Cover and let sit at room temperature for 24 hours until thickened. Stir, then refrigerate for up to a week or two. Though feel free to use sour cream in its place (and let me know how it works - I'm curious!).

This pie likes a long bake, so be sure to protect the edges of the crust with foil (as shown in the tutorial) to prevent them from become overly-caramelized.
