*See notes for Oven Drying Process before beginning. This is what I primarily use currently, but this recipe will detail out a traditional rest method.
Line 2 upside down baking sheets with a silicone mat. Place the scalloped circle template (instructions on how to make it in post) underneath the first silicone mat.
Place a medium/large round piping tip like a 2A in a large piping bag. Twist the bag right behind the tip and add a clip to seal off the opening. Place the bag tip down into either a clean tall cup with the edges folded over the rim to keep the bag open, or clip it into a bag holder.
Pulse the Earl Grey tea in a food processor until it becomes less coarse.
Using a kitchen scale, carefully weigh out and sift the confectioner’s sugar, Earl Grey Tea, and almond flour into a medium mixing bowl. Whisk well to fully blend the three together.
Place egg whites, sugar, and cream of tartar into a large mixing bowl, and begin beating with a whisk attachment using either a handheld mixer or a stand mixer for 3 minutes on a medium low speed (Kitchen Aid Speed 4).
Turn up the mixer to a medium speed (Kitchen Aid Speed 6) and beat for an additional 3 minutes.
Add the green and brown gel food coloring.
Turn mixer up to medium high speed (Kitchen Aid Speed 8) and beat for 3 more minutes, or until peaks are very stiff and the meringue clumps up in a ball in the center of the whisk. Test stiffness by removing whisk and pointing it upward. (See photo in Basic French Macarons post for reference) Once the peaks can hold their shape flipped upright, your meringue is ready.
Pour half of your almond flour/tea/confectioner’s sugar mixture into the bowl with your meringue, and fold 15 times. One fold is scraping all the way around the edge of your batter in your bowl, and then dragging your spatula through the middle to knock out air. Be sure to scoop around the bottom of the bowl as well so you don’t miss any dry ingredients.
Pour in the remaining powdered sugar, tea, and almond flour, and continue folding (approximately 30 more folds) until dry ingredients are fully incorporated. Do not overfold. Start checking your batter’s readiness every 5 folds or so at this point by scraping all batter down to the bottom of your bowl, and then wiggling your bowl back and forth several times. If the batter levels out with very few peaks and lines remaining, it should be ready. (Take note that some shell recipes with flavor add ins can have a bit thicker of a consistency)
Pour batter into prepared piping bag, and twist the opening off. Hold your bag at the twist between your thumb and pointer finger. Remove the clip near the piping tip.
Holding the piping bag straight up and down, apply pressure to begin piping your batter in the center of each scalloped half circle around the edges of the template, releasing pressure once you are a few millimeters short of the outline. After you release pressure, use a small quick circular flick to release your tip from the piped batter.
Pipe a ring of batter around the inner border of the macaron cake layer, leaving once again a few millimeters of space to the edge. Then, pipe the batter in rings to fill in between the scalloped edge and the center ring.
Once you’ve piped the first macaron, firmly bang the tray on the counter a few times to pop any air bubbles and smooth out shells. Pop any remaining large bubbles with a toothpick or scribe tool. Repeat with the second tray and macaron layer.
Begin preheating your oven to 300 degrees, using an oven thermometer to ensure accurate temperature readings.
Set aside the macaron shells to dry until they form a skin and are no longer tacky to the touch. Once you can gently run a finger over your shells, they are ready to bake. Use a fan to speed up the process, rotating the tray every few minutes to ensure even drying. This usually takes 16-20 minutes for me with a fan. (Rest for a shorter amount of time if you deal with high humidity issues)
Once the shells are dry and the oven has fully preheated to 300, place one tray in the center of the middle rack of the oven. Bake for 20 minutes.
Quickly open door to check the shell’s doneness by gently pressing on the side just above the feet to see if it’s firm. If it moves at all, bake for another 2 minutes.
Check shells by performing the same test, pressing on the side. If they are still unstable, bake for one more minute, and check again. Repeat until shells are firm and do not budge, then remove from oven. Make sure oven is still at the correct temperature and then bake your second tray.
Allow shells to cool completely, and the carefully remove from silicone mat by carefully flipping them upside down over on to another tray or flat surface, and gently peeling the mat off. Support the macaron during the flip as much as possible holding the trays on each side without squishing them.
