1. Prepare the Meringue:
   • In a clean, grease-free mixing bowl, beat the egg whites using an electric mixer on medium speed until foamy.
   • Gradually add the granulated sugar, a spoonful at a time, and continue beating until stiff, glossy peaks form.
   • This takes about 8–10 minutes. The meringue should hold a firm point on the beater without collapsing.
2. Sift the Dry Ingredients:
   • In a separate bowl, sift together the almond flour, powdered sugar, and freeze-dried strawberry powder.
   • Discard any coarse bits that remain in the sifter. This ensures smooth macaron tops and proper texture.
3. Combine Wet and Dry (Macaronage):
   • Gently fold the dry mixture into the meringue using a silicone spatula.
   • Continue folding in a figure-eight motion, scraping around the sides and through the middle of the bowl.
   • Stop when the batter flows in ribbons and you can draw a figure-eight without the batter breaking.
4. Add Food Coloring (Optional):
   • Add one drop of fuchsia gel food coloring to intensify the pink tone of the macaron shells.
   • Gently fold until evenly incorporated, without overmixing.
5. Pipe the Shells:
   • Transfer the batter into a piping bag fitted with a round tip.
   • Pipe evenly sized rounds onto a silicone mat or parchment paper-lined baking tray.
   • Tap the tray firmly on the counter 3–5 times to release air bubbles.
6. Rest the Shells:
   • Let the piped shells sit at room temperature for 30–60 minutes until a skin forms on the surface.
   • You should be able to lightly touch them without batter sticking to your finger.
7. Bake:
   • Preheat the oven to 300°F (150°C).
   • Bake for 15–20 minutes. Rotate the tray halfway through to ensure even baking.
   • The macarons are done when they can lift cleanly off the baking mat and have developed characteristic “feet.”
8. Cool Completely:
   • Allow the shells to cool fully on the tray before removing them to avoid sticking or breakage.

Making the Strawberry Buttercream

1. Cream the Butter:
   • In a clean mixing bowl, beat the softened butter until smooth and fluffy.
2. Add the Powdered Ingredients:
   • Gradually beat in the powdered sugar and freeze-dried strawberry powder.
   • Mix until incorporated, scraping down the bowl as needed.
3. Adjust Consistency:
   • Add milk or water 1 tablespoon at a time until the buttercream is smooth and pipeable.

Assembling the Macarons

1. Pair the Shells:
   • Match macaron shells of similar size and shape for a uniform look.
2. Pipe the Filling:
   • Fill a clean piping bag with strawberry buttercream and pipe a small mound in the center of one shell in each pair.
3. Sandwich:
   • Gently press a second shell over the buttercream until the filling spreads evenly to the edges.

Decorating (Optional)

1. Melt the Chocolate:
   • Place white chocolate in a microwave-safe bowl and heat in 15-second intervals, stirring in between until fully melted.
2. Drizzle and Sprinkle:
   • Drizzle melted white chocolate over assembled macarons and immediately sprinkle with powdered freeze-dried strawberry for added texture and visual appeal.
