Method
Make the shells
- Preheat the oven to 300°F and line two 13x18-inch rimmed baking sheets with parchment paper.
- Sift the superfine almond flour and powdered sugar together into a medium bowl.
- Beat the egg whites in a clean bowl with an electric mixer until foamy.
- Add the cream of tartar.
- Gradually beat in the granulated sugar, then continue beating until the meringue is glossy and forms stiff peaks, about 5 to 7 minutes.
- Fold the dry mixture into the meringue in three additions until the batter falls from the spatula in a thick ribbon and settles back into itself in about 10 seconds.
- Transfer the batter to a piping bag fitted with a 1/2-inch round tip and pipe 1 1/4-inch rounds onto the prepared sheets, spacing them about 1 inch apart.
- Firmly tap each sheet on the counter.
- Pop any visible air bubbles with a toothpick.
- Let the shells stand at room temperature for 30 to 60 minutes, until the tops feel dry to the touch.
- Bake one sheet at a time for 14 to 16 minutes, until the shells feel set and do not wobble when gently nudged.
- Cool completely on the sheets, about 20 minutes, before peeling the shells off the parchment.
Make the chai ganache and assemble
- Put the white chocolate in a heatproof bowl.
- Warm the heavy cream, cinnamon, ginger, cardamom, cloves, and black pepper in a small saucepan over medium-low heat until steaming.
- Pour the warm cream mixture over the white chocolate.
- Let stand for 2 minutes.
- Stir until smooth.
- Let the ganache cool at room temperature for 30 to 60 minutes, stirring occasionally, until thick enough to pipe.
- Pair the shells by size.
- Pipe about 1 teaspoon of ganache onto the flat side of half the shells.
- Gently sandwich with the remaining shells.
- Refrigerate the macarons in an airtight container for 12 to 24 hours.
- Bring them to room temperature for 20 minutes before serving.
Notes
For neat shells, fold until the batter falls in a thick ribbon and settles back into itself in about 10 seconds. Refrigerate in an airtight container for up to 5 days; the macarons can also be frozen. For a dairy-free variation, use dairy-free white chocolate and a suitable dairy-free cream.
