Prepare Ingredients: Measure out all ingredients accurately and ensure egg whites are aged and at room temperature.
Sift Dry Ingredients: In a large bowl, sift together almond flour and powdered sugar to remove any lumps.
Whip Egg Whites: Using an electric mixer, beat egg whites on medium speed until foamy. Gradually add granulated sugar and continue beating until stiff peaks form.
Macaronage: Gently fold the dry ingredients into the egg whites in three batches until the batter is smooth and shiny. Add food coloring and flavor extracts if desired.
Piping: Transfer the batter into a piping bag fitted with a round tip. Pipe small rounds onto the prepared baking sheets, leaving space between each macaron.
Resting: Let the piped macarons sit at room temperature for 30-60 minutes until a skin forms on the surface.
Baking: Preheat the oven to 300°F (150°C). Bake the macarons for 12-15 minutes, rotating the trays halfway through baking.
Cooling: Once baked, allow the macarons to cool completely on the baking sheets before gently removing them.
Filling: Pair up macaron shells of similar sizes and sandwich them together with your favorite filling, such as ganache, buttercream, or fruit preserves.
Storage: Store filled macarons in an airtight container in the refrigerator for up to 5 days. Bring to room temperature before serving for the best texture.
