Add dry ingredients to the meringue and start folding in the butter. The batter is ready when you can make a figure 8 with a spatula, or it flows “like lava”.
Transfer the macaronage into a pastry bag with a round tip.
Pipe macaron shells onto the baking mat.
Top the baking sheet pan with pipped macaron shells a few times. Let the shells rest on the countertop until no batter sticks to your finger when you touch it.
Bake macaron shells in the preheated oven at 275°F (134oC) -300oF (150oC) for 12-14 minutes. Oven temperature and baking time may vary, depending on your oven.
Remove baked macaron shells from the oven and let them cool on the baking mat on a baking sheet pan. When the shells are cooled completely cooled, remove them from the baking mat and pair them with similar sizes.
