Ingredients
2 cups unbleached all-purpose flour
1 cup superfine almond flour, such as Bob's Red Mill
1 teaspoon kosher salt
2 sticks unsalted butter, room temperature
1/2 cup confectioners' sugar, plus more for tossing and dusting
1/4 cup granulated sugar
1/2 teaspoon grated orange zest
3/4 cup orange marmalade or other fruit jam
Preparation
Preheat oven to 325°F, with racks in upper and lower thirds. In a medium bowl, whisk together both flours and salt. Beat butter with both sugars and zest in a stand mixer fitted with paddle attachment on medium speed until light and fluffy, about 3 minutes. Reduce speed to low; gradually add flour mixture, beating just until a dough forms.
Scoop dough using a 1 1/8-inch scoop (about 1 1/2 teaspoons); roll into balls and arrange on parchment-lined baking sheets, 1 inch apart. With the tip of your pinkie, create a deep well in center of each ball. Refrigerate 15 minutes.
Bake 10 minutes. Remove from oven; reshape indentations with the tip of the handle of a wooden spoon. Return to oven; bake until cookies are lightly browned on bottoms and set in centers, 8 to 10 minutes more.
Let cool on sheets on wire racks 10 minutes. Gently toss in confectioners’ sugar to lightly coat; let cool completely. Just before serving or packing, sift more confectioners’ sugar over cookies to coat. Bring marmalade to a boil in a small pot. Spoon 1/2 teaspoon into each well. Let stand until marmalade is set, about 15 minutes.
