Nan-e Berenji

Ingredients

2/3 cup confectioners’ sugar
1/2 cup (1 stick) unsalted butter, at room temperature
2 large egg yolks
2 teaspoons rosewater
1 teaspoon ground cardamom
2 cups rice flour, plus more if needed (See Cook’s Note)
Black sesame seeds or poppy seeds, optional

Directions

Beat the confectioners’ sugar and butter in a large bowl with an electric mixer until creamy. Add the yolks and mix until creamy and smooth, about 1 minute. Add the rosewater and cardamom and mix until combined, about 1 minute.

Add the rice flour and stir using a rubber spatula until you have a soft dough that’s still a bit moist, about 3 minutes. If needed, add more rice flour 1 tablespoon at a time. Transfer the dough to a clean bowl, cover tightly with plastic wrap and refrigerate until firm, 4 to 6 hours.

Preheat the oven to 325 degrees F and line a baking sheet with parchment paper.

Scoop 1/2 tablespoon of the dough and roll it into a ball. Place the ball on the prepared baking sheet and gently press it into a 1/2-inch-thick disc. Repeat with the remaining dough, spacing the discs 2 inches apart. Using the edge of a small spoon, gently make a series of curved indentations on top of each disc, radiating out from the center. Sprinkle with sesame seeds (if using).

Bake until the edges start to lightly brown, 8 to 10 minutes. Let cool on the baking sheet for 10 minutes, then transfer the cookies to a wire rack. The cookies keep, refrigerated in an airtight container, for up to 4 days.
