French Macarons

Instructions

1. 1

   Set up and sift

   Line two heavy baking sheets with parchment or silicone mats. Wipe the mixing bowl and whisk with a splash of vinegar or lemon juice on a paper towel to strip away any trace of grease — fat is the single most common reason meringue refuses to whip. Sift the almond flour and powdered sugar together through a fine-mesh sieve into a wide bowl, pressing any stubborn almond bits through with a spoon. Discard whatever gritty pieces absolutely won't pass and replace them with an equal weight of fresh almond flour so your ratio stays honest. Whisk the sifted mixture to combine.

2. 2

   Whip the meringue

   Beat the egg whites on medium speed until they look foamy and opaque, about a minute, then add the cream of tartar and salt. With the mixer running, rain in the granulated sugar about a tablespoon at a time, taking a full minute or two to add it all. Raise the speed to medium-high and whip until the meringue is thick, glossy, and holds a peak that stands straight up when you lift the whisk. It should feel smooth, not gritty, when you rub a little between your fingers. Beat in the vanilla and gel coloring on low for a few seconds — go a shade darker than you want, since the color fades in the oven.

3. 3

   Fold to lava consistency

   Add about a third of the almond mixture and fold it in firmly with a flexible spatula to knock out some air — this first addition can be rough. Add the rest and fold more gently, scraping around the bowl and cutting through the middle, pressing the batter against the side of the bowl every few strokes. Stop frequently and test: lift the spatula and let the batter fall in a thick ribbon. When it flows like slow lava and the ribbon sinks back into the surface within about 15 seconds, stop immediately. Undermixed batter gives lumpy, cracked tops; one or two folds too many gives flat, spreading shells with no feet.

4. 4

   Pipe and rest

   Transfer the batter to a piping bag fitted with a 1/2-inch round tip. Holding the bag straight up about a half inch above the pan, pipe 1 1/4-inch rounds, spaced an inch apart, flicking the tip sideways to cut the flow. Rap each sheet firmly against the counter three or four times to release trapped air, and pop any surface bubbles with a toothpick. Let the piped shells sit out, uncovered, until the tops turn matte and feel dry to a light touch — 30 to 60 minutes in a normal kitchen, longer on a humid day. This skin is what forces the shells to rise upward and form feet.

5. 5

   Bake

   Heat the oven to 300°F (150°C) with a rack in the center and an empty baking sheet preheating on it. Slide one tray of shells directly on top of the hot sheet and bake 15 to 18 minutes, rotating once halfway through. They're done when a shell feels set and barely wiggles when you nudge the top — if the cap slides on the feet, give it another two or three minutes. Cool completely on the pan before attempting to lift any shells; warm macarons tear. Bake the second tray the same way.

6. 6

   Make the buttercream

   Beat the butter alone on medium-high for 2 to 3 minutes, until pale and creamy. Add the powdered sugar in two additions on low speed, then the vanilla, salt, and 1 tablespoon of the cream. Whip on medium-high for 2 minutes, adding the remaining cream only if needed — you want it pipeable but firm enough to hold its shape without oozing out the sides.

7. 7

   Fill and mature

   Sort the cooled shells into matching pairs by size. Pipe a mound of buttercream onto the flat side of one shell, leaving a small border, then set its partner on top and twist gently until the filling just reaches the edge. Seal the filled macarons in an airtight container and refrigerate for at least 24 hours. This maturing step isn't optional — moisture from the filling migrates into the shells and turns them from dry and brittle into that signature crisp-then-chewy bite. Bring to room temperature for 20 minutes before serving.

Baker's Tips

• 1.

  Weigh everything. Macarons are a ratio recipe, and cup measurements of almond flour and powdered sugar vary enough from scoop to scoop to sink a batch.

• 2.

  Separate your eggs while cold (the yolks hold together better), then let the whites sit at room temperature for 30 minutes before whipping.

• 3.

  Even a speck of yolk in the whites will keep the meringue from reaching stiff peaks. Crack each white into a small bowl first, then transfer.

• 4.

  Slide a printed template of 1 1/4-inch circles under your parchment for even sizing, and remember to pull it out before the tray goes in the oven.

• 5.

  Use gel or powdered coloring, never liquid — the extra water loosens the batter and flattens the shells.

• 6.

  Humidity is the enemy. On a damp day the skin can take over an hour to form; a fan pointed across the counter speeds it up considerably.

• 7.

  Hollow shells usually mean the oven ran too hot or the meringue was overwhipped. Check your oven with a thermometer before blaming the recipe.

• 8.

  Leftover yolks keep for two days covered in the fridge — put them toward pastry cream, lemon curd, or a custard-base ice cream.
