The Rebbetzin Chef's Persian Walnut Cookies

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Line 2 baking sheets with parchment paper.

2 . Stage

Mix together ground walnuts, sugar, 3 egg yolks, cardamom, baking soda, and rose water in a medium bowl until well blended. Roll teaspoon-sized pieces of dough into balls and place 2 inches apart onto the prepared baking sheets.

3 . Stage

Whisk together remaining egg yolk and water using a fork. Press a walnut piece into each cookie, then brush with egg yolk glaze.

4 . Stage

Bake in the preheated oven until golden, about 20 minutes. The cookies will appear soft and undercooked but they will harden considerably when cooled.

5 . Stage

Remove from the oven and allow to cool on the baking sheets for at least 10 minutes before transferring to a wire rack to cool completely.
