Rhubarb Strawberry Flaky Galette (Print Version)

# Ingredients:

→ Butter Crust

01 - 155 g all-purpose flour
02 - 140 g cold unsalted butter
03 - 2 tablespoons granulated sugar
04 - 0.25 teaspoon fine salt
05 - 3 tablespoons ice water

→ Rhubarb Filling

06 - 200 g rhubarb, cut lengthwise and into 5 cm pieces
07 - 255 g strawberries, hulled and quartered
08 - 115 g light brown sugar
09 - 2 teaspoons lemon juice
10 - 0.5 teaspoon finely grated lemon zest
11 - 3 tablespoons corn starch
12 - Seeds from 0.5 vanilla bean
13 - 55 g instant oats

→ Finishing and Serving

14 - 1 egg, beaten with 1 teaspoon milk
15 - Coarse sugar, for sprinkling
16 - Vanilla ice cream, for serving

# Instructions:

01 - In a food processor, combine all-purpose flour, granulated sugar, salt, and cold unsalted butter. Pulse for approximately 1 minute, until the mixture forms pea-sized pieces. Gradually add ice water, one tablespoon at a time, pulsing just until the dough holds together.
02 - Transfer dough to a lightly floured surface. Form into a disk, wrap tightly in plastic, and chill in the refrigerator for at least 1 hour.
03 - In a bowl, thoroughly combine rhubarb, strawberries, light brown sugar, lemon juice, lemon zest, corn starch, and vanilla seeds.
04 - Roll the chilled dough on a lightly floured surface to form a rough circle, about 0.5 cm thick. Carefully transfer to a baking sheet lined with parchment paper.
05 - Sprinkle instant oats evenly over the dough, then pile the fruit mixture in the center, leaving a border of 4 cm. Fold the edges of the dough up and over the fruit, overlapping slightly for a rustic look.
06 - Transfer the baking sheet with the formed galette to the freezer and chill for 15 minutes to set the shape.
07 - While the galette chills, preheat oven to 190°C.
08 - Remove the galette from the freezer. Brush the crust with beaten egg and milk mixture, then sprinkle generously with coarse sugar.
09 - Bake in the preheated oven until the crust is deeply golden and the filling is bubbling, about 40–45 minutes.
10 - Allow to cool briefly. Slice and serve warm with a scoop of vanilla ice cream.

# Notes:

01 - Chilling the assembled galette in the freezer before baking helps maintain a flaky, crisp crust.
02 - A combination of rhubarb and strawberries balances tartness and sweetness for optimal flavor.
