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 Filling
- ½ cup fresh key lime juice
- ½ cup unsalted butter (softened)
- Additional ¼ cup powdered sugar (for filling)
Instructions
- Preheat Oven: Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper to prevent sticking and ensure even baking.
- Sift Dry Ingredients: Sift together the powdered sugar and almond flour twice to create a fine, smooth mixture essential for the delicate macaron shells.
- Whip Egg Whites: Beat the aged egg whites until frothy. Gradually add the granulated sugar while continuing to beat until stiff peaks form, creating a glossy and stable meringue.
- Fold Mixture: Carefully fold the sifted dry ingredients into the meringue using a spatula until the batter reaches a lava-like consistency – fluid but not runny.
- Pipe Shells: Pipe small, evenly sized circles onto the prepared baking sheet. Tap the tray gently to release any trapped air bubbles for smooth tops.
- Bake Shells: Bake for 15-20 minutes until the macarons develop characteristic feet but remain pale on top. Allow them to cool completely on the baking sheet before handling.
- Prepare Filling: In a bowl, beat the softened butter until creamy. Gradually mix in powdered sugar and fresh key lime juice until smooth and spreadable.
- Assemble Macarons: Pipe the key lime filling onto the flat side of half the cooled macaron shells and gently sandwich with the remaining shells, pressing lightly to adhere without breaking.
Notes
- Allow egg whites to age for 24 hours in the refrigerator at room temperature for improved meringue stability.
- Sifting dry ingredients ensures your macarons have a smooth texture without lumps.
- Be gentle when folding to preserve the airiness of the meringue but mix enough to achieve the desired batter consistency.
- Macarons are sensitive to oven temperature; monitor baking times closely to avoid browning.
- The key lime filling can be refrigerated for up to 3 days or frozen for longer storage.
