Line 2 large baking sheets with Silpat mats or parchment paper. Fit a piping bag with a small round tip (like a Wilton #10).
Create a simple double-boiler by setting a heatproof bowl over a small saucepan of simmering water.
Add the egg whites and granulated sugar to the bowl. Whisk constantly until the sugar has fully dissolved, about 3-4 minutes.
3 large egg whites, ½ cup granulated sugar
Transfer the egg white mixture to the bowl of a stand mixer fitted with the whisk attachment. Beat on medium-high speed until they form stiff peaks.
Sift the powdered sugar and almond flour into the beaten egg whites. Fold the mixture gently to incorporate the dry ingredients into the egg whites.
⅘ cup powdered sugar, 1 cup almond flour
When about half of the dry ingredients have been incorporated, add pink gel food coloring, if using, and continue folding.

Gently deflate the meringue by smushing it against the sides of the bowl and folding it back together. Repeat the smushing process 3-4 times and then test the meringue to see if it’s at the “figure 8 stage”. If you can draw an 8 with the batter while it flows smoothly, it’s ready. If the meringue falls off in clumps or breaks during the “8”, smush it 1-2 more times and fold it back together. Then repeat the figure 8 test.
When the batter flows smoothly, transfer the mixture to the piping bag fitted with a round tip. Pipe 1½-inch circles about 2 inches apart on the prepared baking sheet.
Immediately after you’ve finished piping the tray, hold it 6 inches off the counter and drop it straight down to release any air bubbles. Repeat the dropping process 5-6 times, or until it looks like any large air bubbles have popped.
Set the tray aside to rest for 20-25 minutes, or until the macarons have developed a skin. The macarons are ready to bake when they can be gently touched without sticking to your finger.
While the macarons rest, preheat your oven to 325°F. Bake the macarons one tray at a time for 14-16 minutes, flipping the tray halfway through baking.
Allow the macarons to cool on the tray. Once they are fully cooled, they can be filled and aged.
