Old-Fashioned Melt-In-Your-Mouth Walnut And Citrus Cookies

1. 1

   Preheat oven to 300 degrees F. Line 2 large cookie sheets with parchment paper.

2. 2

   Cream butter, sugars and citrus zest in a bowl with a hand-hold mixer or a wooden spoon until light and fluffy. Mix in egg yolks one at a time. Add flour and salt mixture, and then walnuts. Mix just until dough comes together and is well combined.

3. 3

   Shape dough into a disk, wrap in plastic, and chill in refrigerator until firm, 30 to 40 minutes.

4. 4

   Roll out the dough on a lightly floured surface into about 1/4 inches thick round. Using any shape and size you like or have cookie cutters, cut out dough pieces and place them about 1 inch apart on the baking sheets. Reroll scraps, chilling dough if it gets too soft.

5. 5

   Bake both pans with cookies at the same time until golden, changing positions in oven halfway through, 20 to 25 minutes. Let cool on a rack.

6. 6

   These cookies will keep fresh up to 3-4 days stored in airtight containers.
