Equipment

  • Measuring Cups and Spoons
  • Mixing Bowl
  • 9 inch tart pan

Ingredients
  

  • 1 1/2 cup (180 g) all-purpose flour Provide structure and a tender crumb to the tart shell; combine with fat and liquid to form a workable dough, and help absorb moisture during baking to ensure the crust holds its shape.
  • 1/2 cup (100 g) powdered sugar Add fine sweetness and promote a delicate texture in the pastry; sift with flour to prevent lumps and keep the crust light without adding graininess.
  • 1/2 teaspoon salt Enhance overall flavor balance and bolster other ingredients; stabilize the dough by regulating gluten development and subtly brightening the pastry's taste.
  • 10 tablespoons (140 g) unsalted butter melted Contribute rich fat and moisture to the crust; when melted and mixed with flour and sugar, create flakiness and help bind the dough for easy pressing into the tart pan.
  • 5 large egg yolks at room temperature Provide concentrated richness and a silky texture to the lemon custard; enrich the filling, add color, and help thicken when combined with other eggs and heat.
  • 3 large eggs at room temperature Supply body and additional thickening power to the curd-like filling; add volume, creaminess, and structure to ensure a smooth, set lemon tart interior.
  • 1 cup (200 g) granulated sugar Sweeten and balance the tart's acidity; dissolve with eggs and lemon juice to create a glossy, stable filling while controlling sweetness level.
  • 2 teaspoons cornstarch cornflour in the UK Act as a thickening agent to stabilize the lemon filling; prevent curd from becoming runny by binding liquids and creating a smooth, satiny texture once heated.
  • 1/2 teaspoon salt Round out flavor and season both crust and filling; when used sparingly, improve taste perception and enhance the contrast between sweet and tart components.
  • 2 tablespoons grated lemon zest Deliver concentrated lemon oil and aromatic intensity to the filling; incorporate finely into the custard to boost bright citrus flavor without adding extra liquid.
  • 1/2 cup + 2 tablespoons (150 ml) lemon juice freshly squeezed (about 4-5 lemons, depending on the size) Provide the primary tart and acidic component for the curd; react with eggs and sugar to set the filling and create the signature lemon flavor profile.
  • 10 tablespoons (140 g) unsalted butter Add creaminess and a glossy, smooth finish to the filling; when melted into the curd, contribute richness, body, and a slightly softer set for a luscious bite.
  • 3 tablespoons (45 ml) heavy whipping cream Increase richness and slightly loosen the filling for a silkier texture; whipping cream folded or stirred in tempers sharpness and enhances mouthfeel.
  • Fresh berries, whipped cream, or powdered sugar optional, to garnish Offer optional garnish and finishing touches to the plated tart; add color, freshness, or light sweetness that complements the lemon filling and enhances presentation.

Instructions
 

  • Preheat the oven to 350°F (180°C), or 160°C fan oven.: You should feel the kitchen warm as the oven comes up to temperature, and a reliable preheat ensures the crust begins baking immediately for a crisp base. I always place the rack in the lower third so the bottom gets direct heat, helping avoid a soggy center. A common mistake is skipping preheat, which can cause uneven baking. If your oven runs hot or cold, use an oven thermometer to check accuracy.
  • In a medium bowl, whisk together flour, sugar and salt. Add melted butter and using a spatula, mix until combined.: The mixture should smell faintly of sweet butter and feel like coarse crumbs as you stir. This step builds the foundation for a tender crust; the melted butter binds the dry ingredients without chilling, which makes pressing easier. If you overmix, the dough can become dense, so stop once it comes together. Watch for greasy pockets of butter which indicate uneven distribution.
  • Add 1/2 of the flour mixture to a 9-inch (23 cm) tart pan with a removable bottom. Using your hands and the flat bottom of a measuring cup, press the mixture evenly into the bottom of the pan and just starting up the sides. Press the remainder of the mixture into the fluted sides, connecting to the bottom crust. Use your hands to make sure the crust is evenly spread in the edges of the pan, even on top, and with the aid of the measuring cup, even on the bottom. The measuring cup can be used to ensure the joint of the sides and bottom are straight against the pan.: As you press, you should hear a faint brushing sound and feel the dough compact under firm pressure, forming a uniform layer. A well pressed crust ensures slices keep their shape. Take care to make the thickness consistent, since thin areas will bake faster and risk burning. If the dough sticks to your hands, chill briefly rather than adding more flour, which would dry the crust.
  • Line the crust dough with parchment paper or aluminum foil and fill with pie weights, dried beans or rice work well. Bake the crust for 15 minutes, remove the paper and weights, and continue to bake for an additional 10 minutes. Carefully remove from the oven and set on a cooling rack.: While baking you will notice the edges turn a pale golden tone and the aroma of toasted butter will rise. Removing the weights lets the bottom brown and crisp fully. A frequent pitfall is skipping the second bake, which leaves the bottom underdone. Allow the crust to cool on a rack so steam can escape and the base keeps crispness rather than steaming against the pan.
  • In a medium bowl, whisk eggs and egg yolks together and set aside.: The eggs should look smooth and slightly pale when whisked, with no pockets of yolk remaining. This uniformity helps them temper evenly when introduced to the warm lemon mixture. Use room temperature eggs so they integrate without shocking them into curdling. If eggs are cold, tempering will be harder and can lead to lumps.
  • In a small saucepan, whisk together sugar, cornstarch, salt, and lemon zest. Add lemon juice and butter and cook on medium heat, stirring often until the mixture just starts to bubble.: The mixture will smell intensely lemony from the zest and you will see small bubbles around the edge as the liquid heats. Stirring prevents scorching and ensures the cornstarch dissolves fully. You want it to bubble briefly, not boil vigorously, because too high heat can over thicken or change the flavor. If it thickens too rapidly or sticks to the pan, lower the heat and whisk continuously.
  • Remove the pan from heat and slowly pour the lemon mixture into the eggs, whisking constantly. Transfer curd to a new small or medium saucepan, whisking constantly over medium-low heat until the curd starts to thicken and coat the back of a spoon, this takes several minutes.: As you temper, the combined aroma of warm citrus and butter becomes richer and more rounded. Coating the back of a spoon is the visual cue that signals proper thickness. Continuous whisking prevents ribbons of cooked egg and keeps the texture silky. A common error is adding hot liquid too fast, which cooks the eggs into scrambled bits; go slowly and stir without stopping.
  • Place a fine-meshed sieve over a medium-sized bowl and strain the curd into the bowl. Stir in the cream and pour the curd into the warm crust.: Straining removes any tiny cooked particles, producing a glossy, pillowy curd. After passing through the sieve, the curd should glide like custard and smell fragrant and balanced. Stirring in the heavy whipping cream adds silk and softens the tang, making the texture luxurious. If the curd seems grainy after straining, it may have overheated; gentle whisking off heat can help smooth it.
  • Bake the filled tart in the 350°F/180°C oven for 10 minutes to set the tart. Take it out of the oven and place on a cooling rack to cool to room temperature, for about 1-2 hours.: During this brief bake the surface should look just set and retain a glossy sheen, not cracked or dry. Cooling on a rack prevents trapped steam and keeps the crust from getting soggy. If you rush to chill it while it is still very warm, condensation may form under the wrap, making the filling watery. Be patient and allow the tart to reach room temperature before chilling further.
  • Serve at room temperature or carefully cover with plastic wrap, refrigerate for 3-4 hours or overnight, and serve chilled. Once cooled, before serving, remove the outer ring from the pan and using a thin metal spatula, slide it between the bottom crust and the tart pan bottom and carefully transfer it to the serving plate.: Chilled slices hold cleaner shapes and the flavors round out after resting. When unmolding, you should feel a slight slip as the removable rim lifts away, and the tart will look glossy and smooth. Avoid forcing the tart from the pan if it resists; chilling a bit longer usually helps. Use a thin, flexible spatula and steady hands to prevent cracking.
  • The lemon tart can be served plain, sprinkled with powdered sugar, garnished with fruit, or with whipped cream and fruit.: The final presentation is where you add personality, whether that is a dusting of powdered sugar or a neat crescent of fresh berries . The contrast of tart filling and light garnish enhances both appearance and taste. One mistake is overdoing heavy toppings which can mask the lemon’s brightness; keep garnishes balanced and complementary.

Notes

  • Measure ingredients accurately, especially the flour and butter, to maintain the right dough consistency; spoon the flour into the cup instead of scooping to prevent compacting.
  • Keep the butter warm but not hot when combining with dry ingredients, so it binds without cooking the mixture and makes pressing into the pan easier.
  • Temper the eggs slowly by pouring the warm lemon mixture into the eggs in a slow stream while whisking, which prevents curdling and keeps the filling smooth.
  • Use fresh lemon juice and zest for the most vibrant flavor, and strain the juice to remove any pulp that might create texture in the curd.
  • Sieve the curd after cooking to remove any tiny cooked bits and to ensure a silky finish that will set and slice cleanly.
  • Chill for cleaner slices by refrigerating for at least three hours, and remove the tart ring gently with a thin spatula to transfer it without cracking.
