Masaryk's Cookies

First, prepare the dough. In a medium-sized bowl, combine flour, sugar, butter, and egg yolk and mix everything thoroughly until the ingredients form a firm dough. Then add the hazelnuts and work them into the dough. Shape the prepared dough into 1 large or 2 smaller rolls (approx. 3 cm in diameter), wrap in cling film and let rest for at least 8 hours (preferably overnight).

Once the dough has rested, preheat the oven to 170 °C, prepare a baking sheet and line it with baking paper. Remove the film from the roll, lightly coat it in cane sugar, and slice into rounds approximately 0.7 cm thick. Arrange the rounds on the baking paper, place the baking sheet in the oven, and bake until golden for 18–22 minutes at 170–175 °C.
