Make the Dough:
In a stand mixer, sift flour into a bowl.
In a separate bowl, whisk together hot water, vegetable oil, salt, and vodka (if using).
Add the liquid mixture to the flour and mix using a dough hook on medium-low speed until a soft, non-sticky dough forms. Adjust with a little more flour or water if needed.
Cover and let the dough rest for 30 minutes.
Prepare the Filling:
In a food processor, blend onion, garlic, salt, pepper, paprika, cayenne, parsley, and ice-cold water until pureed.
Mix this puree into the ground meat until well combined. Set aside.
Shape the Chebureki:
Divide the rested dough into 12 equal balls. Cover with a towel.
Roll out one ball into a thin 8-inch circle.
Spread 3 tbsp of meat filling over half of the dough, leaving a slight edge.
Fold over the dough to form a half-moon shape.
Seal edges by pressing with fingers, then crimp with a fork. Trim any uneven edges if needed.
Fry the Chebureki:
Heat ½-inch of vegetable oil in a skillet or cast iron pan to 375°F (190°C).
Fry chebureki in batches for 2-3 minutes per side until golden brown and crispy.
Transfer to a paper towel-lined plate to drain excess oil.
Serve:
Enjoy warm with sour cream or your favorite dipping sauce!
