Craving a show-stopping treat that combines the lightness of French macarons with the vibrant zing of lemon? These Lemon Poppy Seed Macarons are just what you need!
Prepare the double boiler: Add 1-2 inches of water to a saucepan and bring to a simmer. Place a heatproof glass bowl on top, ensuring it doesn't touch the water.
Make the curd: In the glass bowl, whisk together egg yolks, sugar, lemon juice, zest, and salt until well combined. Continue whisking constantly while the mixture cooks to prevent curdling.
Cook: Whisk the lemon curd for 10-20 minutes, or until it thickens and becomes paler. If it’s not thickening, increase the heat slightly and keep whisking.
Finish the curd: Once thickened, remove from heat. Stir in the butter until fully combined and smooth. If desired, strain through a fine mesh sieve and transfer to a jar. Allow it to cool at room temperature, then store in the fridge.
Macaron Shells:
Prepare dry ingredients: Sift together almond flour and powdered sugar into a large bowl. Stir in poppy seeds and set aside.
Whisk the egg whites: In a stand mixer, whisk egg whites on medium speed until foamy. Add cream of tartar and increase the speed to medium-high. Gradually add granulated sugar, ensuring it’s added slowly to avoid deflating the meringue.
Form stiff peaks: Once all sugar is added, increase to the highest speed and whisk until stiff peaks form.
Combine wet and dry ingredients: Gently fold half of the sifted dry ingredients into the meringue. Then fold in the remaining dry ingredients. Mix until the batter reaches a smooth, "lava-like" consistency. It should flow easily and form a figure-eight without breaking.
Pipe the shells: Line a baking sheet with a silicone mat or parchment paper. Fit a piping bag with a ½-inch round tip and pipe 1-inch rounds onto the mat. Gently tap the baking sheet on the counter 3-4 times to release any air bubbles, and use a toothpick to pop any remaining bubbles.
Rest the shells: Let the macarons sit at room temperature for 30-40 minutes or until a skin forms on top, and you can lightly touch them without disturbing the surface.
Preheat oven: While resting, preheat your oven to 300°F.
Bake: Bake the macarons for 15 minutes, one sheet at a time, on the center rack. The macarons are done when they don’t move on their feet when touched.
Cool: Let the macarons cool completely on the baking sheet before removing them. Once cool, match the shells into pairs.
Assemble the Macarons:
Fill the shells: Pipe a small amount of cooled lemon curd into the center of one macaron shell, leaving a little room at the edges. Top with the other shell.
Mature the macarons: Store the assembled macarons in an airtight container and refrigerate them for 12-24 hours before serving for the best flavor and texture.
Notes:
Clean the stand mixer and whisk attachment with lemon juice to remove any fat residue that could affect the meringue.
Macarons can be stored in an airtight container in the fridge for up to 5 days, while the lemon curd can be kept for up to 2 weeks in the fridge.
