8 oz finely shredded sharp cheese
1/2 stick unsalted butter at room temp
3/4 tsp kosher salt
1 c flour
2 Tbsp ice water
In bowl of mixer mix cheese, butter and salt until soft and combined. Add flour and mix on low. Slowly add the water and mix until dough forms a ball. Pat the dough onto a disk. Wrap tightly with plastic and refrigerate for at lease an hour.
Preheat oven to 375•. Line baking sheets with parchment paper.
Divide dough in half. Roll very thin 1/8 inch or less. Cut into one inch square and poke center with chopstick then transfer to baking sheets and bake 15-18 min. 15 was perfect for mine bit watch last few min as they can burn easily.
