Preheat the oven to 350 F. Line 2 baking sheets with parchment paper or silicone mats.

Combine the cornmeal, salt, flour and sugar in a food processor until evenly mixed. Pulse in the lemon zest. Add the butter and pulse until it looks like coarse sand.

Pulse in the 2 egg yolks and the extracts until evenly mixed in and the dough starts to come together around the processor blade.

Remove the dough onto a clean workspace. Knead for 1-2 minutes, until the dough comes together--it will be dense and sticky.

Use a cookie press to press the dough onto into shaped cookies 1-2 inches apart on the cookie sheets.

Bake for around 7 minutes--the cookies are done when they begin to brown at the edges. Let them cool completely on the cookie sheets.
