212 grams almond meal
212 grams confectioners’ sugar
82 and 90 grams egg whites, divided
236 grams granulated sugar, plus a pinch
158 grams water
Buttercream or ganache, for filling
Preheat the oven to 350˚ F and place a rack in the middle of the oven. Line baking sheets with parchment paper. In a large bowl, combine the almond meal and confectioners’ sugar. Whisk together to blend and break up any clumps. (You may also use an equal weight of blanched or slivered almonds and grind them in a food processor, but I much prefer the convenience of almond meal, not to mention I think it ultimately results in a better texture.) Make a well in the center of the dry ingredients and pour in 82 grams of the egg whites. Blend the egg whites into the dry ingredients until evenly mixed. The mixture will be thick and paste-like.
Meanwhile, combine the sugar and water for the syrup in a small saucepan over medium-high heat with a candy thermometer clipped to the side. When the temperature is around 200˚ F, combine the 90 gram portion of egg whites with a pinch of sugar. Begin whipping on medium-low speed. Continue whipping the whites on medium speed until they form soft peaks. If soft peaks are achieved before the syrup reaches the target temperature, reduce the speed to low to keep the whites moving.
Once the syrup reaches 248˚ F, immediately remove it from the heat. Increase the mixer speed to medium and pour the syrup down the side of the bowl in a slow drizzle until fully incorporated. Increase the mixer speed to medium-high and whip the meringue until stiff, glossy peaks form. (If you are going to add color to the macaron shells, this is the time to do so. Gel or powdered food colors should be used.)
Add one third of the meringue mixture to the bowl with the almond mixture. Fold in gently until the mixture is smooth. A bit at a time, gently fold in the remaining meringue until the batter is smooth and runs in thick ribbons off of the spatula. You may not need all of the meringue, so add it gradually. (I typically use most but not all of it.) Add the batter to a pastry bag fitted with a plain round tip with about a ½-inch opening. Hold the bag perpendicular to the baking sheet about ½-inch above the surface of the pan. Steadily pipe rounds about 1¼- to 1½-inches in diameter. The batter may create small peaks immediately after piping, but if it is the correct texture these will smooth themselves away after a minute or two. If the batter is too stiff, the peaks will remain and the tops of the shells may not be totally smooth. If the batter is too thin, the rounds will spread further.
Transfer the baking sheet to the oven and immediately reduce the temperature to 325˚ F. Bake for 9-12 minutes, until the tops are smooth and set and “feet” have formed around the bottom. Let the shells cool just briefly on the baking sheet, maybe 5 minutes or so, and then peel away from the parchment. They should come away easily and fully intact. Transfer to a cooling rack. Repeat as needed with the remaining batter, replacing the parchment paper with each batch. (Bring the oven temperature back up to 350˚ F before baking a second sheet, and proceed as before.) Once the shells are baked and cooled, match them up in pairs by size and sandwich with the filling of your choice. Store in an airtight container.
