Method
Make the shells
- Heat the oven to 300°F with a rack in the center.
- Line two 18x13-inch baking sheets with parchment paper.
- Sift the almond flour, confectioners' sugar, and nutmeg into a bowl, then set aside.
- Beat the egg whites in a clean bowl on medium speed until foamy.
- Gradually add the granulated sugar, then beat on medium-high until the meringue is glossy and holds stiff peaks, about 5 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 within about 10 seconds.
- Transfer the batter to a piping bag fitted with a 1/2-inch round tip and pipe 40 rounds about 1 1/4 inches wide, about 20 per sheet.
- Tap each sheet firmly on the counter and pop any visible air bubbles with a toothpick.
- Let the shells stand at room temperature for 30-60 minutes, until the tops feel dry and do not stick to a fingertip.
- Bake one sheet at a time for 14-16 minutes, until the tops are set and do not wobble when gently nudged.
- Cool the shells completely on the baking sheets, about 20-30 minutes, before lifting them from the parchment.
Make the eggnog ganache
- Put the white chocolate in a heatproof bowl.
- Heat the eggnog in a small saucepan over medium heat just until steaming.
- Pour the steaming eggnog over the chocolate and let stand for 2 minutes.
- Stir the chocolate and eggnog until smooth.
- Refrigerate for 45-60 minutes, stirring every 15 minutes, until thick enough to pipe.
Assemble the macarons
- Pipe or spread ganache onto the flat side of half the shells.
- Top with the remaining shells and press gently to make sandwiches.
- Refrigerate the macarons in an airtight container for at least 12 hours and up to 3 days.
- Bring the macarons to room temperature for 20 minutes before serving.
Notes
For smooth shells, fold only until the batter falls in a thick ribbon and settles back within about 10 seconds. Refrigerate in an airtight container for up to 3 days; freezing is not recommended for best texture. For a dairy-free variation, use dairy-free white chocolate and dairy-free eggnog.
