Corn Flour Lemon Cookies

Preheat oven to 350 degrees F. In the bowl of a stand mixer with the paddle attachment, add the flours, sugar, butter, lemon zest and a pinch of salt. Mix on medium speed until the dough starts to form. Add the 4 egg yolks, 1 at a time, and mix briefly, just to incorporate. Spoon the dough onto a piece of parchment paper and roll into a log shape. Let the dough rest in the refrigerator for 30 minutes. Unroll dough from parchment paper and slice into half-inch thick cookie rounds. Place the rounds onto an un-greased cookie sheet and sprinkle with the finely chopped almonds. Bake for 10 to 12 minutes. The cookies should be set and light golden brown.
