Ingredients

• for the tart crust:
• 1 ½ cups all-purpose flour, sifted
• ½ cup unsalted butter, cold and cubed
• ⅓ cup granulated sugar
• ¼ tsp salt
• 1 egg yolk
• 2-3 tbsp ice water
• For the lemon custard filling:
• 1 cup fresh lemon juice (about 5-6 lemons)
• 1 tbsp lemon zest (finely grated)
• 1 ½ cups granulated sugar
• 4 large eggs

• 1 ¼ cups water
• 2 tbsp unsalted butter, cubed
• For the meringue topping:
• 4 large egg whites, at room temperature
• ½ tsp cream of tartar
• ½ cup granulated sugar
• 1 tsp vanilla extract

Instructions

1. Prepare the tart crust: In a food processor, pulse flour, sugar, and salt to combine. Add cold cubed butter and pulse untill mixture resembles coarse crumbs. Add egg yolk and 2 tablespoons of ice water, pulsing until dough starts to come together. Add more water if needed, 1 tsp at a time.
2. Turn dough onto a floured surface and form into a disc.Wrap in plastic and refrigerate for at least 30 minutes.
3. Preheat oven to 350°F (175°C). Roll out chilled dough to fit a 9-inch tart pan with removable bottom. Gently press dough into pan and trim excess. Chill for 10 minutes.
4. Line tart shell with parchment and fill with pie weights or dried beans. Bake blind for 15 minutes. Remove weights and parchment; bake an additional 10 minutes until golden. Let cool.
5. Make the lemon custard: In a medium saucepan, whisk together lemon juice, lemon zest, sugar, eggs, cornstarch, and water until smooth.
6. Place over medium heat, whisking constantly until mixture thickens and starts to bubble-about 8 minutes. Remove from heat and stir in butter until melted and smooth. Pour custard into cooled tart shell and smooth top. Chill while preparing meringue.
7. Prepare the meringue: Using a stand mixer, beat egg whites and cream of tartar on medium speed until soft peaks form.
8. Gradually add sugar, 1 tablespoon at a time, increasing to high speed until stiff, glossy peaks form. Beat in vanilla extract.
9. Spread meringue over chilled lemon filling, ensuring it touches the edges of the crust to seal.
10. Bake at 350°F (175°C) for 10-12 minutes or until meringue is golden brown.
11. Cool to room temperature, then refrigerate for at least 1 hour before serving to allow flavors to meld.

tips for Success

• Use fresh lemons for vibrant flavor; bottled lemon juice lacks the same brightness.
• Ensure the tart dough is cold to prevent shrinking during baking.
• Whisk the custard constantly when cooking to avoid lumps and prevent scorching.
• When making meringue, room-temperature egg whites whip better and achieve more volume.
• To avoid weeping meringue, make sure the lemon custard is fully cooled before topping.
• The meringue should be spread carefully so it seals the edges, preventing shrinkage and moisture loss.
• Make the tart a day ahead to allow custard to set perfectly and meringue flavors to meld.

The Science Behind Balancing Flavors and textures

The allure of lemon meringue tart lies in its balance of tart and sweet, crisp and fluffy. The buttery crust provides a sturdy yet tender foundation, countering the custard’s vibrant acidity without overwhelming it. Simultaneously occurring, the meringue offers a contrasting texture-light, airy, and creamy-providing sweetness without cloying richness. Achieving this harmony demands respecting the science of ingredient interactions: the custard’s gel-forming cornstarch, the meringue’s egg white structure stabilized with cream of tartar, and the crust’s gluten network all play critical roles for the ideal bite.
