Ingredients
Scale
Macaron Shells
- 1 ¾ cups powdered sugar
- 1 cup almond flour
- 3 large egg whites (aged)
- ¼ cup granulated sugar
- Food coloring (optional)
Key Lime Buttercream Filling
- ½ cup unsalted butter (softened)
- ½ cup fresh key lime juice
- Extra powdered sugar (about ¼ cup) mixed into buttercream during beating for texture
Instructions
- Preheat Oven and Prepare Baking Sheet: Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper to prevent sticking.
- Sift Dry Ingredients: Sift together the powdered sugar and almond flour twice to remove lumps and achieve a fine, smooth mixture essential for perfect macarons.
- Whip Egg Whites: Beat the aged egg whites until frothy, slowly add the granulated sugar, and continue whipping until stiff peaks form, creating a glossy meringue that will give the macarons their structure.
- Fold Dry Mix into Meringue: Carefully fold the almond flour and powdered sugar mixture into the meringue using a spatula in a folding motion until the batter resembles flowing lava, ensuring it’s well incorporated but not overmixed.
- Pipe Macaron Shells: Transfer the batter to a piping bag and pipe small circles onto the prepared baking sheet. Tap the sheet firmly on a surface to release trapped air bubbles for smooth tops.
- Bake the Shells: Bake the macarons in the preheated oven for 15 to 20 minutes until they develop the characteristic ‘feet’ and remain pale in color. Allow to cool completely on the sheet before handling.
- Prepare Key Lime Filling: Beat the softened butter until creamy, then gradually mix in powdered sugar and fresh key lime juice to create a tangy, smooth buttercream filling.
- Assemble Macarons: Pipe the key lime buttercream onto half of the cooled macaron shells, then sandwich with the remaining shells gently pressing together to create bite-sized treats.
Notes
- Use aged egg whites (left uncovered in the refrigerator for 24-48 hours) for better meringue stability.
- Ensure almond flour and powdered sugar are finely sifted to avoid gritty texture.
- Macarons can be stored in an airtight container in the refrigerator for up to 3 days to enhance flavor and texture.
- Allow assembled macarons to rest at room temperature for about 30 minutes before serving for the filling to soften slightly.
