Age Your Egg Whites (12–24 hours)
Crack egg whites into a bowl and let them sit uncovered in the fridge overnight. This helps reduce moisture, making them whip up stronger.
Prep Dry Ingredients (10 minutes)
Sift almond flour and powdered sugar together 2–3 times. Discard any large lumps. (Smooth shells depend on fine flour.)
Make the Meringue (10–15 minutes)
In a clean, grease-free bowl, beat egg whites on medium speed. Add cream of tartar once foamy. Gradually add granulated sugar until stiff peaks form. Add vanilla and food coloring at this stage.
Macaronage (Folding Batter) (5 minutes)
Gently fold the dry ingredients into the meringue with a spatula. Continue folding until the batter flows like lava—thick but pourable. Test by making a figure 8 with the batter—it should flow without breaking.
Pipe the Shells (10 minutes)
Transfer batter into a piping bag fitted with a round tip. Pipe 1.5-inch circles onto a parchment-lined baking sheet. Tap the tray on the counter 4–5 times to release air bubbles.
Rest the Shells (30–60 minutes)
Let the piped shells sit at room temperature until they form a “skin.” You should be able to touch the top lightly without batter sticking.
Bake the Macarons (15–18 minutes)
Preheat oven to 300°F (150°C). Bake for 15–18 minutes, rotating halfway. They’re done when they have firm tops and the famous “feet” (ruffled edges).
Fill the Macarons (10 minutes)
Once cooled, pair shells by size. Pipe buttercream (or your chosen filling) onto one shell, then sandwich with another.
Mature the Macarons (24 hours)
Store in an airtight container in the fridge for 24 hours. This allows flavors to meld and texture to improve.
