• 1 large egg
• 5 large egg yolks
• 1/3 cup honey
• Pinch of kosher salt
• 4 tablespoons unsalted butter, cut into small cubes and chilled
• 2 tablespoons heavy cream

Blueberry Topping:

• 10 ounces (around 2 cups) fresh blueberries
• 2 tablespoons cornstarch
• 1/4 cup honey

• Pinch of kosher salt

Prep and Equipment:

• 9-inch tart pan with removable bottom
• Food processor or mixing bowls
• Fine mesh strainer
• Rolling pin
• Pie weights or dried beans

Step-by-Step Instructions

1. Prepare and Chill the Dough
   • In a small bowl, whisk together the egg yolk, cream, and vanilla extract.
   • In a food processor, combine the flour, confectioners’ sugar, and salt. Pulse to mix.
   • Add the chilled butter cubes and pulse several times until the mixture looks like coarse crumbs.
   • Add the egg mixture and pulse just until the dough starts to come together.
   • Turn the dough out onto a clean surface, form into a disk, wrap in plastic, and refrigerate for at least 1 hour.
2. Roll and Blind-Bake the Crust
   • Let the chilled dough sit at room temperature for 10 minutes to soften slightly.
   • Lightly flour your work surface and roll the dough into an 11-inch circle.
   • Press the dough into the tart pan and trim the edges. Use a fork to lightly prick the bottom.
   • Freeze the tart shell for 30 minutes to prevent shrinkage during baking.
   • Preheat the oven to 375°F (190°C).
   • Line the crust with foil and fill with pie weights.
   • Bake for 30 minutes, rotating halfway through.
   • Remove the foil and weights, then bake for another 5–10 minutes until golden and crisp.
   • Let cool completely on a wire rack.
3. Make the Lemon Curd
   • Lower oven temperature to 350°F (175°C).
   • Reserve 1 tablespoon of lemon juice and set aside for the blueberry layer.
   • In a saucepan, whisk together the lemon zest, lemon juice, whole egg, egg yolks, honey, and a pinch of salt.
   • Cook over medium-low heat, stirring constantly with a heatproof spatula, until the curd thickens and reaches 165°F (about 5–6 minutes).
   • Remove from heat and immediately whisk in the chilled butter until melted and smooth.
   • Strain the lemon curd through a fine mesh strainer into a clean bowl.
   • Stir in the heavy cream for added richness and silkiness.
   • Pour the curd into the cooled tart crust and gently shake to level.
   • Bake for 10–12 minutes until the filling is just set with a slight jiggle in the center.
   • Let cool completely on a rack at room temperature.
4. Prepare the Blueberry Glaze
   • In a blender or food processor, puree the blueberries until smooth.
   • Pour the mixture through a fine sieve into a saucepan to remove skins and seeds.
   • Add the honey and a pinch of salt to the strained puree.
   • In a small bowl, mix cornstarch with 2 tablespoons cold water to form a slurry.
   • Stir the slurry into the blueberry mixture.
   • Cook over medium-low heat, stirring constantly, until the mixture thickens, about 4–5 minutes.
   • Remove from heat and stir in the reserved tablespoon of lemon juice.
   • Allow the topping to cool to room temperature.
5. Assemble and Chill the Tart
   • Spoon the blueberry topping evenly over the lemon curd layer.
   • Use a spatula to gently spread it to the edges.
   • Tap the tart lightly on the counter to eliminate air bubbles.
   • Refrigerate for at least 2 hours to set before serving.

Beginner Tips and Notes

• Chill for Success: Cold dough is easier to handle and won’t shrink in the oven. Freeze the shaped crust before baking for best results.
• Prevent Soggy Crust: Make sure the tart shell is baked until golden and crisp. A fully cooled shell also prevents curd from softening the base.
• Smooth Curds Every Time: Strain both the lemon curd and blueberry topping to remove any cooked egg bits or fruit skin for a smooth finish.
• Honey Tips: Use a mild honey so it doesn’t overpower the fruit flavors. Clover or wildflower honeys work well.
• Use a Thermometer: Lemon curd is ready when it reaches 165°F. This guarantees it’s thickened and safe to eat.
• No Food Processor? Cut the butter into the flour by hand using a pastry cutter or two forks until the texture resembles sand.

Serving Suggestions

• Best Chilled: Serve the tart directly from the refrigerator for a refreshing, cool dessert.
• For Clean Slices: Use a sharp knife dipped in hot water and wiped clean after each cut to get perfect portions.
• Add a Topping: Garnish with fresh blueberries, lemon slices, or a sprinkle of powdered sugar right before serving.
• Pair with Drinks: Goes well with black tea, herbal infusions, or light sparkling beverages.
• Dessert Plating: Add a dollop of whipped cream or Greek yogurt beside each slice for contrast and visual appeal.

Engagement Features

• Try Variations: Replace blueberries with raspberries or blackberries for a different berry flavor. Try a chocolate crust or almond shortbread base for a twist.
• Make It Your Own: Add herbs like fresh thyme or basil to the blueberry topping for an unexpected aromatic touch.
• Batch and Freeze: Make and freeze the tart shell in advance. Store baked shells in an airtight container or wrap in foil and freeze for up to 1 month.

• Gift Idea: Wrap in a tart box or clear container, tie with ribbon, and bring as a hostess gift or birthday surprise.
