Sift the Almond Flour and Confectioner’s sugar. Whisk well to incorporate.
Take your stand mixer bowl and wipe clean with a dab of vinegar to ensure its clean. Add egg whites. Attach your whisk attachment, whisk the egg whites until foamy, about a minute or so, then slowly add the sugar. Whisk until stiff peaks are formed, about 4-5 minutes.This is the meringue. At 3 minutes, add the gel coloring.
Add a third of the meringue to the flour and Confectioner’s sugar and with a rubber spatula fold. Repeat until all is added.
Fill a piping bag and prepare a baking sheet or two with baking paper or method of choice. Pipe around 2-inch circles. Use a french macaron piping template for convenience. Bang the pans on the counter top a couple times all around to get rid of bubbles.
Preheat oven to 325°F. Let the Macarons dry on your counter top for about 20 minutes until the shiny surface becomes dull and a skin is formed.
Turn down your oven to 300°F and bake the Macarons for around 15-16 minutes. Let cool for at least 10 minutes.
