   ["Place the almond flour and 1-1/2 cups plus 3 Tbsp. (175 grams) confectioners' sugar in a food processor; pulse until thoroughly mixed to ensure almond flour is very fine. Pass almond flour mixture through a fine-mesh sieve; discard any large pieces that remain.", "Place egg whites in a very clean bowl of a stand mixer fitted with whisk attachment; whisk on medium-low speed until frothy. Slowly add superfine sugar; whisk until dissolved, 1-2 minutes. Slowly add remaining confectioners' sugar; increase speed to high and whip until meringue is glossy and stiff peaks form, 2-3 minutes.", "Gently fold one-third of the almond flour mixture into meringue; gently fold in remaining almond flour in 2 additions. Using side of spatula, smooth batter up sides of bowl several times to remove air bubbles and ensure there are no lumps; do not overmix. Run spatula down the center of the bowl; the line in the batter should remain visible for a moment before mixture runs back into itself.", "Position rack in upper third of oven; preheat oven to 300\u00b0. Transfer batter into a pastry bag fitted with a #7 or #10 round tip. Pipe 1-3/8-in. rounds onto parchment about 1 in. apart. Tap tray against counter 2-3 times to remove excess air bubbles. Let macarons rest until no longer wet or sticky to the touch, 30-60 minutes. Bake, 1 tray at a time, until cookies rise about 1/8-in. to form \"feet
