Green Papaya Tart

Steps

1. 1

   Make the shortbread crust

   • Combine all-purpose flour, powdered sugar, and ¼ tsp (1.5g) of the salt in a food processor.
   • Pulse to combine evenly.
   • Add cold butter cubes and pulse 8–10 times until the mixture resembles coarse breadcrumbs with some pea-sized pieces of butter still visible.
   • Add the egg yolk and vanilla extract and pulse just until the dough comes together—stop as soon as it looks cohesive, as overmixing will make the crust tough.
   • Turn the dough into a 9-inch (23 cm) tart pan with a removable bottom and press it evenly over the bottom and up the sides, creating an even ⅛-inch layer.
   • Use the flat bottom of a measuring cup to help press firmly.
   • Chill in the freezer for 15 minutes while you preheat the oven.

   Ready when: Dough pressed evenly into pan with no gaps; appears pale and uniform

   Tip: Keep butter as cold as possible and work quickly—this ensures a flaky, tender crust

2. 2

   Blind bake the crustOven 375°F / 190°C

   • Preheat oven to 375°F (190°C).
   • Remove the chilled tart crust from the freezer.
   • Line the inside of the crust with parchment paper and fill with baking beans or dried rice, pressing them gently against the bottom and sides.
   • Bake for 12–15 minutes until the edges are light golden brown.
   • The bottom doesn't need to be fully baked yet.
   • Carefully remove the parchment and weights, watching for steam.
   • If the bottom seems wet or pale, return to the oven for 2–3 minutes to dry it slightly.
   • Remove from oven and let cool on a rack for 5 minutes while you reduce the oven temperature to 350°F (175°C).

   Ready when: Edges are light golden; crust is set and holds together firmly

   Tip: Parchment and weights prevent the crust from puffing up unevenly

3. 3

   Prepare the custard fillingOven 160°F / 70°C

   • In a medium mixing bowl, whisk together the 3 large egg yolks and ¼ cup (50g) palm sugar until the mixture is pale and slightly thickened, about 1–2 minutes.
   • Add 3 tablespoons (45ml) of the lime juice and the lime zest, whisking until fully combined.
   • Pour the heavy cream into a small saucepan and gently heat over medium heat until wisps of steam rise and the temperature reaches about 160°F (70°C); don't let it boil.
   • While whisking the egg yolk mixture constantly, slowly pour the warm cream into the yolks in a thin stream to prevent scrambling.
   • In a small cup, whisk the cornstarch with 1 tablespoon of cold water until smooth.
   • Add this slurry and ⅛ teaspoon of salt to the custard, whisking until no lumps remain.
   • Pour the entire filling through a fine-mesh sieve into a clean bowl to remove any cooked bits of egg.

   Ready when: Custard is pale, smooth, and passes through sieve without lumps

   Tip: Add warm cream slowly while whisking to prevent scrambling; sieving gives the silkiest texture

4. 4

   Bake the filled tartOven 350°F / 175°C

   • Pour the strained custard filling into the cooled, blind-baked tart crust, filling to about ¼ inch below the rim.
   • Place the tart pan on a baking sheet (for easier handling).
   • Bake at 350°F (175°C) for 15–18 minutes.
   • The filling is done when the edges appear set and opaque, but the very center still jiggles slightly like soft custard when you gently tap the baking sheet.
   • The filling will continue to set as it cools.

   Ready when: Edges are set and opaque; center jiggles slightly like custard

   Tip: Slight jiggle in the center prevents overbaking, which makes custard rubbery and prone to cracking

5. 5

   Cool the tart completely

   • Remove the tart from the oven and place it on a wire cooling rack.
   • Let it cool undisturbed at room temperature for about 20 minutes as the custard continues to set.
   • Transfer the tart to the refrigerator and chill for at least 30 minutes until the custard is completely firm and cold to the touch.
   • The tart can be made ahead to this point.

   Ready when: Filling is completely firm; no jiggle when tart is moved

   Tip: Chilling makes the custard firmer and assembly with papaya easier

6. 6

   Make the palm sugar-lime glaze

   • In a small saucepan, combine the remaining 2 tablespoons (30g) palm sugar, 2 tablespoons (30ml) lime juice, and 2 tablespoons (30ml) water.
   • Bring to a gentle simmer over medium-low heat, stirring occasionally, until the sugar is completely dissolved and the mixture is clear, about 2–3 minutes.
   • The liquid should flow off a spoon in a light syrup.
   • Remove from heat and let cool to room temperature, about 5–10 minutes.
   • The glaze will thicken slightly as it cools but should remain pourable.

   Ready when: Sugar fully dissolved; glaze is clear and flows off a spoon

   Tip: Don't boil aggressively or the glaze may crystallize

7. 7

   Slice and arrange the green papaya

   • Remove the tart from the refrigerator.
   • Using a vegetable peeler, peel the fresh green papaya.
   • Use a sharp knife or small spoon to scoop out the soft seeds from the central cavity.
   • Slice the papaya flesh into very thin, translucent slices about ⅛ inch (3 mm) thick.
   • A mandoline slicer works beautifully, but a sharp chef's knife works fine—aim for uniform, paper-thin slices.
   • Arrange the papaya slices on the custard filling in an overlapping pattern, starting at the outer edge and working toward the center in a spiral.
   • The slices should overlap by about half.

   Ready when: Papaya slices are neatly arranged in overlapping pattern

   Tip: Slice papaya as thin as possible for an elegant appearance; arrange no more than 2 hours before serving

8. 8

   Finish and serve the tart

   • Lightly brush or drizzle the cooled palm sugar-lime glaze over the papaya-covered tart using a pastry brush or small spoon, coating the papaya slices evenly.
   • If using fresh Thai basil, tear the leaves gently and scatter them over the tart just before serving.
   • Serve the tart chilled or at room temperature.
   • To slice, use a sharp thin-bladed knife dipped in hot water and wiped dry between cuts to cleanly slice through the tart without smudging the filling.

   Ready when: Glaze coats papaya evenly; tart is ready to serve

   Tip: A hot, wet knife gives you clean slices without smudging the custard
