Strawberry Rhubarb Lattice Pie

June in my grandmother's kitchen meant one thing: rhubarb plants taller than me, their crimson stalks waiting in the garden patch. She'd hand me a basket and tell me to pick the reddest ones, already planning that magical pie where strawberries met their tart soulmate. That first bite of bubbly, sweet-tart filling under a golden crust still tastes like childhood summers and windows flung open to catch the evening breeze.

Last summer I made this for a 4th of July gathering, watching from the kitchen window as my friends' children played tag through the backyard. When I carried the cooling pie outside, the group went quiet for a moment before someone whispered 'that smells like heaven'. That night we ate it still slightly warm, vanilla ice cream melting into every crevice, and I understood why certain foods become bookmarks in our memories.

Ingredients

• All-purpose flour: The foundation for a tender, flaky crust that holds together while staying delicate
• Cold butter: Essential for creating those coveted flaky layers, keep it ice-cold and cut into small pieces
• Ice water: Adds just enough moisture to bring the dough together without making it tough
• Fresh strawberries: Look for bright red, fragrant berries that give slightly when gently squeezed
• Fresh rhubarb: Choose crisp, firm stalks with deep red color for the best tart flavor and beautiful hue
• Granulated sugar: Balances the rhubarb's natural acidity while letting the fruit flavors shine
• Cornstarch: Thickens the fruit juices into that perfect luscious filling that oozes slightly but holds its shape
• Cinnamon: Adds warmth and depth without overpowering the bright fruit flavors
• Egg and milk: Create that gorgeous golden sheen on the crust while helping the sugar stick

Instructions

Make the pie crust dough:

Whisk flour with sugar and salt in a large bowl, then work in cold butter using a pastry blender until you see pea-sized pieces scattered throughout. Drizzle ice water over the mixture a tablespoon at a time, gently tossing with your hands until the dough holds together when squeezed. Divide into two disks, wrap tightly, and let chill in the refrigerator for at least an hour so the gluten relaxes.

Prepare the luscious filling:

In a large bowl, combine sliced strawberries and chopped rhubarb with granulated sugar, cornstarch, cinnamon, and a pinch of salt. Add vanilla extract and lemon juice, tossing everything gently until the fruit is evenly coated. Let this mixture sit while you roll out the crust, allowing the sugars to start drawing out the fruit's natural juices.

Roll out the bottom crust:

Preheat your oven to 400°F and roll one disk of chilled dough on a lightly floured surface until it's about 12 inches in diameter. Carefully transfer it to your 9-inch pie pan, letting the edges drape over the sides. Trim any excess hanging dough, leaving about an inch overhang for sealing the top crust later.

Add the fruit filling:

Pour the strawberry-rhubarb mixture into the prepared crust, spreading it evenly. Pay attention to any accumulated juices at the bottom of the bowl and pour those over the fruit too. The filling might look generous, but remember it will cook down significantly in the oven.

Weave the lattice top:

Roll the second disk of dough and cut it into strips about 3/4 inch wide. Lay half the strips vertically across the pie, spacing them evenly. Fold back every other strip and place a horizontal strip across the center, then repeat this weaving process, folding and alternating strips until you have a beautiful checkerboard pattern.

Finish and bake the pie:

Trim and crimp the edges to seal everything together, then whisk egg with milk and brush this mixture over the entire lattice crust. Sprinkle coarse sugar generously across the top for that bakery sparkle and crunch. Bake at 400°F for 20 minutes, then reduce heat to 350°F and continue baking for another 35 to 40 minutes until the crust is deep golden and the filling bubbles vigorously through the lattice.

My most cherished memory of this pie comes from my first apartment kitchen, where I nervously invited my new neighbors over for dessert. One of them took a bite, closed her eyes, and said 'this tastes exactly like my grandmother used to make'. That moment of connection over shared flavors made that tiny kitchen feel like home.

The Secret to Tender Lattice Strips

Keep your dough strips chilled while you work. If they start feeling soft or sticky, pop the whole pie in the refrigerator for 10 minutes. Cold dough maintains clean edges and doesn't shrink during baking, giving you those professional-looking lattice lines that make people think you have secret pastry training.

Timing Your Fruit Selection

I've learned that the best strawberry rhubarb pies happen when strawberries are at their peak sweetness and rhubarb is still young and tender. Late spring to early summer is the sweet spot. Using fruit that's traveled halfway across the world and sat in cold storage will give you a pie that's merely good, not the transcendent experience this dessert can be.

Serving Suggestions That Elevate

While vanilla ice cream is the classic companion, I've discovered that a dollop of crème fraîche adds a lovely tang that echoes the rhubarb. A scoop of strawberry ice cream creates a beautiful double-strawberry effect that strawberry lovers can't resist. For dinner parties, serve slightly warm slices with small glasses of cold heavy cream on the side for guests to pour themselves.

• Leftover pie keeps well at room temperature for 2 days, covered loosely with foil
• For breakfast, nothing beats a cold slice of this pie alongside hot coffee
• The flavors actually deepen and improve after the first day, if it lasts that long

There's something profoundly satisfying about serving a pie you made from scratch, watching friends' eyes light up at that first golden-topped slice. This strawberry rhubarb beauty has become my go-to for bringing people together, one buttery, tart-sweet bite at a time.

Recipe Questions & Answers

→ How do I make the lattice crust?

Roll out the dough and cut it into 3/4-inch strips. Lay half vertically, then weave horizontal strips over and under to form a lattice pattern. Trim and seal the edges before baking.

→ Can I substitute the fruit in the filling?

Yes, you can replace some strawberries with raspberries for a different flavor. Frozen fruit can be used if thawed and drained well.

→ What thickens the filling?

Cornstarch is used in the filling to thicken the fruit juices and maintain a firm texture after baking.

→ How do I ensure a flaky crust?

Keep butter cold when mixing and don’t overwork the dough. Chilling the dough before baking helps maintain flakiness.

→ What can I use instead of the egg wash?

Plant-based milk can substitute egg wash for brushing the crust’s surface, though it may affect browning slightly.
