Step 1

In a small bowl using an electric hand mixer on high, beat egg yolks, sugar and salt until thick and lemon colored - about a minute.

Step 2

On low speed, mix in sour cream, vanilla, liquor and flour. Stir in enough additional flour to form a mass (usually a couple tablespoons)

Step 3

Transfer to a floured surface and knead 50 turns (about 2 minutes), adding extra flour as needed.

Step 4

Divide dough in half, keeping extra covered with plastic.

Step 5

On a well floured surface, roll each section paper-thin to at least 12” across. Cut into 1 1/4-inch wide strips. Cut strips into 5-inch lengths. Make a slit in the center of each strip. Pull one end through slit to make a "bow tie".

Step 6

Deep fry in oil at about 350-360 F for about 15 seconds each side, turning once using 2 forks, until lightly golden on both sides.

Step 7

Drain on paper towels. Let cool and sprinkle with powdered sugar.

Step 8

To re-crisp place on baking sheet in a 325° oven for about 5 minutes. Cool completely and re-dust with fresh powdered sugar.
