Makes about 25 to 30 macarons
XIAOLU'S NOTES: Please do not try to convert this recipe to volume measurements if you don't have a scale (I use and love this one). This recipe is very sensitive and will not work if the measurements are not exact. Please also note that every oven is different and you'll figure out what works best for yours over time (see this post for great information on ovens and macarons). Since mine has major hot spots, I bake on 2 stacked pans for insulation if using parchment paper. If you're uncertain of your ability to pipe uniformly-sized macarons, like me, simply trace 1 1/4-inch circles on your parchment paper, flip the paper over, and pipe on the other side, using the outlines as your guide OR print (choose "fit to page") and slide this template under your parchment as a guide but don't forget to remove before baking! See my first macaron post for helpful videos of the whole macaron-making process!
125 g almonds [not roasted or salted]
170 g powdered sugar
1/4 tsp amchoor (Indian dried green mango) powder [optional]
Large pinch of salt
35 g granulated sugar
2 g egg white powder [optional, to stabilize batter in humid weather]
Splash of white or cider vinegar [to clean utensils/stabilize meringue]
90 to 95 g egg whites [about 3 large egg whites]
Orange food coloring (powder or gel) [optional]
5 oz. mascarpone cheese, cool room temperature
1 Tbsp heavy cream
2 Tbsp powdered sugar, sifted
1/2 cup finely diced ripe mangoes
Microwave fresh egg whites 10 to 15 seconds in the microwave on medium-low heat (I set my microwave to 40%).
Combine the almonds, powdered sugar, mango powder, and salt in a food processor, and pulse on and off until the nuts are finely ground (about 1 to 2 minutes). Sift the powder to remove any large chunks that remain. Put those chunks back into the food processor and pulse again for another 30 to 60 seconds. Sift again. You will probably have some slightly chunkier almond bits. Hopefully they're no more than a tablespoon or so, in which case you can throw them out.
Weigh out and mix your granulated sugar and egg white powder in a small bowl until uniform; set aside. Add splash of vinegar then a splash of water to the bowl that will be used for whipping the egg whites. Swirl liquid around the bowl, then use a clean paper towel to wipe the bowl dry. Use the same paper towel to wipe down your beaters. Now using a handheld or stand mixer, whip the egg whites on medium-low speed until foamy, then turn the speed up to medium to medium-high and gradually add the sugar mixture. Now add orange food coloring, if using, until the desired shade is reached (color will lighten once fully whipped). Continue whipping until you obtain a glossy meringue (it'll look like shaving cream, hold stiff peaks, and stay in place if you turn the bowl upside-down; but don't overbeat your meringue or it will be too dry).
Add all of the nut mixture to the meringue and fold together. Use both a folding motion that scrapes the bottom of the bowl (to incorporate the dry ingredients) and a gentle pressing motion, to deflate the meringue against the side of the bowl. Slow down after all the dry ingredients have been incorporated, and continue folding the mass carefully until you obtain a batter that looks somewhat glossy and flows from the spatula in a thick ribbon. Test the batter by spooning a small amount of the batter on a plate: if the top flattens on its own within about 20 seconds, it’s ready to pipe. If there is a small peak, give the batter 2 to 3 more folds and test again. The peak shouldn’t disappear immediately either or it’s already overmixed.
Fill a pastry bag fitted with a 1/3 to 1/2-inch wide plain tip (I like Ateco #805 or 806) with half of the batter. (When your bag is too full, the pressure causes the batter to rush out in a way that’s difficult to control, making for sloppy macarons.) Pipe tiny blobs of batter onto the 4 corners and center of 2 baking sheets, then line baking sheets with parchment paper OR line with silicone mats. Pipe small rounds (slightly larger than 1 inch wide) straight down and about 1 inch apart onto the baking sheets. Pick up each sheet with both hands and slam it firmly straight downward on the counter 2 to 3 times. This will to force out any large air bubbles. Immediatelypop any bubbles that rise up but don't break with a toothpick. Do NOT do this once a few minutes have passed because you'll mess up the shell that's forming.
Preheat the oven to 285 to 300 degrees F. Let the macarons sit out for 25 to 90 minutes to harden their shells a bit (to prevent tops from cracking during baking). Test if they're ready by touching the top and side of one shell lightly. It should feel dry and not stick to your finger at all. Bake one pan at a time for 15 to 25 minutes, depending on the size of the macarons. After the first 10 minutes of baking, rotate the pan and place a large piece of foil loosely over the macarons to prevent browning (If I’m baking on 2 stacked pans, I also remove the bottom pan at this point to make sure the macarons will be completely cooked on the bottom and not sticky). Let cool completely before trying to move the shells.
Once cool, remove the shells from the silicone mat or parchment and flip them over. If you have trouble removing them, freeze the macarons for about 10 minutes, then quickly peel them off before they have a chance to warm up and get sticky again.
To prepare the filling, combine the mascarpone, powdered sugar, and heavy cream and mix well. To fill, spoon or pipe about 1 teaspoon of mascarpone mixture onto half the macaron shells, sprinkle with diced mangos, then top with a similarly-sized top shell. For the best flavor and texture, store in the refrigerator for at least 1 hour before eating so flavors are allowed to mature, but they are best if eaten within 2 days. Bring to cool room temperature before eating.
