Chrusciki

Step 1
Whisk egg yolks, egg, sugar, whiskey, salt, and vanilla together in a bowl. Stir in 2 cups flour. If dough is sticky, stir in remaining 1/2 cup flour. Knead dough on a lightly floured surface for 5 minutes. Divide into thirds and cover with plastic wrap.

Step 2
Heat 1 inch oil in a deep-fryer or large saucepan to 375 degrees F (190 degrees C).

Step 3
Working with one piece of dough at a time, roll on a lightly floured surface until paper-thin. Cut into parallelograms (long diamonds); use a sharp paring knife to cut a slot in the center of each, and pull one point of the diamond through the slot. Repeat to make remaining cookies.

Step 4
Fry two to four pieces at a time, depending on the size of your pan, until crisp but not browned, 5 to 10 seconds per side. Drain on paper towels and dust with confectioners' sugar when cool.
