Strawberry Rhubarb Lattice Pie

My grandmother grew rhubarb in her garden behind the garage, the red stalks towering like celery from another planet. She would snap them off at the base and hand them to me to rinse at the outdoor spigot, the tart smell already staining my fingers. We would bake pies on rainy June afternoons when the strawberries at the farm stand were at their sweetest. Those rainy baking days taught me that some flavor combinations exist for a reason.

I brought this pie to a Memorial Day potluck last year, still slightly warm from the oven. The host cut into it and the filling spilled out onto the cutting board, everyone gasping like something had gone wrong. But then she tasted that first bite, the juices running down her chin, and suddenly nobody cared about perfect presentation. Three people asked for the recipe before they even finished their slices.

Ingredients

• 2 1/2 cups all purpose flour: The structure that holds everything together, do not substitute whole wheat here or you will lose tenderness
• 1 cup unsalted butter cold and cubed: Cold butter is nonnegotiable for flaky layers, I keep mine in the freezer for 15 minutes before starting
• 1 tsp salt: Enhances all the flavors without making the crust taste salty
• 1 tbsp sugar: Just enough to help the crust brown and give a subtle sweetness
• 6 to 8 tbsp ice water: Add this gradually, some days you need more, some days less, trust your hands
• 2 1/2 cups fresh rhubarb sliced: Look for stalks that are firm and deeply colored, avoid ones that are too thick or woody
• 2 1/2 cups fresh strawberries hulled and quartered: Pick berries that smell fragrant, they should be slightly soft but not mushy
• 1 cup granulated sugar: This balances the extreme tartness of rhubarb, do not reduce or your filling will be too sour
• 1/4 cup cornstarch: The thickener that transforms juicy fruit into sliceable pie filling
• 1/4 tsp salt: A pinch that intensifies the fruit flavors
• 1 tsp vanilla extract: Use the good stuff, it makes a noticeable difference in the filling
• 1 tbsp lemon juice: Brightens everything and helps the strawberries hold their color
• 2 tbsp unsalted butter cut into small pieces: Tucked into the filling, these melt into little pockets of richness
• 1 egg: For the egg wash that gives your crust that golden bakery shine
• 1 tbsp milk: Thins the egg for easier brushing
• 1 tbsp coarse sugar: The crunch on top makes each bite feel special

Instructions

Make the dough your new weekend ritual:

Whisk flour, salt, and sugar in a large bowl, then work in cold butter with your fingers until you see pea sized chunks. Sprinkle ice water over the top, tossing gently with your hands until the dough holds together when squeezed. Divide into two disks, wrap tightly, and chill for at least one hour or overnight.

Let the fruit mingle:

Combine rhubarb, strawberries, sugar, cornstarch, salt, vanilla, and lemon juice in a large bowl. Let this sit for 15 minutes while you roll out your crust, the sugar will draw out just the right amount of juice.

Roll out the bottom crust like a pro:

Flour your counter and rolling pin generously, then roll one dough disk into a 12 inch circle, rotating frequently to prevent sticking. Fold it into quarters and transfer to your pie dish, then unfold and press gently into the corners.

Build the foundation:

Pour the fruit mixture into the crust, including all those gorgeous juices at the bottom of the bowl. Scatter the small butter pieces over the top.

Weave that lattice top:

Roll the second disk and cut into one inch wide strips. Lay half the strips in parallel lines across the pie, then fold back every other strip and weave perpendicular strips through, repeating until you have created a basket pattern.

Give it some golden shine:

Whisk egg with milk in a small cup until combined, then brush generously over the lattice. Sprinkle coarse sugar over the top for that bakery finish.

Bake to perfection:

Preheat your oven to 400°F, place the pie on a baking sheet to catch any drips, and bake for 20 minutes. Reduce to 350°F, tent loosely with foil, and continue baking for 35 to 45 minutes until the filling bubbles thickly in the center.

Practice patience:

Let the pie cool completely on a wire rack for at least two hours before slicing. This is the hardest part but absolutely essential for clean slices.

Last summer my neighbor brought over a bowl of rhubarb from her garden, saying she had too much and did not know what to do with it. I invited her over to make this pie together, her hands covered in flour as she learned to weave the lattice for the first time. We sat on her back porch eating still warm slices with vanilla ice cream, watching the fireflies come out as the sun went down.

The Perfect Crust Every Time

I have learned that pie dough knows when you are stressed, so approach it with a light touch and cold hands. If the butter starts melting into the flour, stop and put everything in the refrigerator for 15 minutes. The shaggy mess that looks like it will never come together usually makes the most tender crust.

Seasonal Swaps That Work

When rhubarb season ends, I make this with all strawberries or switch to peaches and blueberries in July. The key is keeping the total fruit amount the same and adjusting sugar based on natural sweetness, less for ripe fruit and more for tart varieties.

Serving Suggestions

This pie deserves to be the star of the show, served slightly warm with quality vanilla ice cream that melts into all those nooks and crannies. A cup of strong coffee or herbal tea cuts through the richness perfectly.

• Whipped heavy cream with a drop of vanilla makes an elegant alternative to ice cream
• Aged balsamic vinegar drizzled over strawberries before baking adds complexity
• This pie keeps well at room temperature for one day, then refrigerate for up to three days

There is something deeply satisfying about pulling a lattice topped pie from the oven, the golden crust and jewel toned filling making all that effort worthwhile.

Questions & Answers

→ How do I prevent the crust from becoming soggy?

Chilling the dough before rolling and baking at a high initial temperature helps set the crust, while blind baking the bottom crust slightly can reduce sogginess from the filling juices.

→ What makes the lattice crust special?

The lattice crust allows steam to escape and adds a decorative touch. Weaving strips creates an appealing pattern that crisps beautifully during baking.

→ Can I substitute the strawberries or rhubarb?

Yes, you can swap strawberries with raspberries or other berries, but adjust sugar to taste since different fruits vary in sweetness and acidity.

→ Why add cornstarch to the filling?

Cornstarch acts as a thickener, absorbing excess juices released by the fruit during baking to produce a firm, sliceable filling.

→ How long should the pie cool before slicing?

Cooling for at least two hours on a wire rack allows the filling to set properly, ensuring clean and stable slices.

→ Is it necessary to brush the top with egg wash?

Egg wash creates a shiny, golden finish on the lattice crust and helps any sugar sprinkled on top to adhere and caramelize.
