Ingredients

• Oven Temp: 375°F / 190°C
• Crust
• 1 ½ cups (180g) all-purpose flour
• ¼ cup (50g) granulated sugar
• ½ teaspoon salt
• ½ cup (113g) cold unsalted butter, cut into small cubes
• 1 large egg yolk (or 1-2 tablespoons ice water, if needed)
• Filling
• 4 cups (approx. 450g) fresh rhubarb, trimmed and cut into ½-inch (1.25 cm) pieces (Choose firm, crisp stalks. Trim off leaves, as they are toxic.)
• ½ cup (100g) granulated sugar (Rhubarb varies in sourness; you can adjust slightly to taste, but remember it's meant to be tangy!)
• 2 tablespoons (20g) finely ground almonds (This creates a lovely barrier and subtle flavor. Semolina is another great option if you prefer.)
• 2 large eggs
• ½ cup (120ml) whole milk or half-and-half
• ½ teaspoon vanilla extract
• Pinch of salt
• Equipment
  9-inch tart pan with removable bottom
  Rolling pin
  Large mixing bowls
  Whisk
  Sheet pan (to catch any drips during baking)

Directions

1. Prep the Rhubarb: Wash and trim the rhubarb stalks, removing any leaves. Cut the stalks into ½-inch (1.25 cm) pieces. If your rhubarb seems extra juicy, you can lightly pat it dry with a paper towel, but a little moisture is normal. Set aside.
2. Make the Crust Dough: In a large bowl, whisk together the flour, sugar, and salt. Add the cold butter cubes and, using your fingertips or a pastry blender, cut the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining. Add the egg yolk and mix until the dough just comes together. If it's too dry, add a tiny bit of ice water, a teaspoon at a time. Be careful not to overmix; you want to keep the butter cold for a flaky crust.
3. Chill, Roll, & Fit the Pan: Form the dough into a disk, wrap it in plastic wrap, and chill in the refrigerator for at least 30 minutes. Once chilled, lightly flour a clean surface and your rolling pin. Roll the dough into a 12-inch (30 cm) circle, about ⅛-inch (3 mm) thick. Carefully transfer the dough to your 9-inch tart pan, pressing it gently into the bottom and up the sides. Trim any excess dough from the edges. Patch any small tears with extra dough. Place the tart pan on a sheet pan.
4. Par-bake Decision: For this recipe, we're going with a quick par-bake to help prevent a soggy bottom. Prick the bottom of the crust all over with a fork. Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 10 minutes at 375°F (190°C). Remove the weights and parchment, then bake for another 5 minutes until the crust looks dry and lightly set. This quick par-bake helps create a protective layer.
5. Add the Juice Barrier Layer: Once the crust is par-baked, sprinkle the finely ground almonds evenly over the bottom of the warm crust. This layer acts as a fantastic barrier, absorbing excess moisture from the rhubarb and further preventing a soggy bottom – a key idea for a perfect tart!
6. Arrange Rhubarb & Sweeten: Evenly arrange the cut rhubarb pieces over the almond layer in the tart shell. Try to keep it in a single layer without too many large piles, as this helps it cook evenly. Sprinkle the ½ cup of granulated sugar evenly over the rhubarb.
7. Mix Custard & Pour: In a medium bowl, whisk together the eggs, milk (or half-and-half), vanilla extract, and a pinch of salt until well combined. Carefully pour this custard mixture over the rhubarb in the tart shell. Don’t overfill; the custard should come just to the top of the rhubarb and crust.
8. Bake: Place the sheet pan with the tart on the middle rack of your preheated oven. Bake for 40-45 minutes, or until the custard is set and the rhubarb is tender.
9. Cool: Once baked, remove the tart from the oven and let it cool completely on a wire rack. Cooling is crucial for the custard to fully set, ensuring clean, beautiful slices.
10. Doneness Cues (Super Practical!):
    1. Custard Jiggle Test: Gently tap the side of the tart pan. The custard in the center should have only a slight jiggle, like gelatin, not a liquid wobble.
    2. Crust Color: The edges of the crust should be golden brown.
    3. Rhubarb Softness: The rhubarb should be tender when pierced with a knife or fork.
