Ingredients:
Lemon Curd:
⅔ cup lemon juice
3 large eggs
5 tablespoons white sugar
1 tablespoon lemon zest
3 ½ tablespoons salted butter, cut into small pieces
Cupcakes:
1 ¼ cups all-purpose flour
¾ cup white sugar
1 ½ teaspoons baking powder
½ teaspoon salt
½ cup milk
¼ cup vegetable oil
½ teaspoon vanilla extract
1 large egg
½ cup hot water
Meringue:
½ cup white sugar
3 large egg whites
¾ teaspoon lemon juice
Instructions:
-Combine lemon juice, eggs, sugar, and lemon zest for lemon curd in a small saucepan over low heat. Cook, whisking constantly, until thick enough to coat the back of a spatula or spoon, about 10 minutes. Remove from the heat and strain through a sieve into a bowl. Stir in butter until melted; set aside.
-Preheat the oven to 350 degrees F (175 degrees C). Line a 12-cup muffin tin with paper liners.
-Sift flour, sugar, baking powder, and salt for cupcakes into a large bowl. Pour milk, oil, vanilla extract, and egg onto the dry mixture. Mix thoroughly with an electric mixer of by hand. Pour in hot water and mix to combine; batter will be thin. Spoon batter into the prepared muffin liners, filling about 3/4 full.
-Bake in the preheated oven until tops spring back when lightly pressed, 15 to 18 minutes. Cool in the tin for 5 minutes. Transfer to a wire rack and let cool, about 20 minutes.
-Core each cupcake using either a corer or a knife. Spoon in lemon curd.
-Pour sugar and egg whites into a large bowl. Place the bowl over a saucepan or pot of simmering water. Whisk constantly until sugar is dissolved and egg whites are warm, to between 120 and 140 degrees F (49 to 60 degrees C) on a thermometer, 4 to 6 minutes. Remove from the heat.
-Mix in lemon juice and whip at high speed until stiff peaks form. Pipe meringue onto the cupcakes.
-Set an oven rack about 10 inches from the heat source and preheat the oven’s broiler.
-Place cupcakes under the preheated broiler until meringue has browned, about 2 minutes.
