nutmeg maple butter cookies

INGREDIENTS

• 1 cup (2 sticks or 226 grams) unsalted butter, at room temperature
• 1 cup (200 grams) granulated sugar
• 1/2 cup (118 ml) maple syrup (Grade B is ideal here, but the original recipe suggested that Grade A with a few drops of maple extract would also work)
• 1 large egg yolk
• 3 cups (375 grams) all-purpose flour
• 1/2 teaspoon freshly grated nutmeg or 1/4 teaspoon ground nutmeg (because it packs more tightly)
• 1 1/4 teaspoon flaky salt or 1 teaspoon table salt
