Make the dough - In a large mixing bowl, combine flour, yeast, and salt. Slowly add warm water and stir until a soft dough forms. Knead the dough with your hands until it is smooth and elastic. Coat the dough with 1 tablespoon of vegetable oil, cover the bowl with plastic wrap, and let it rest for 30 minutes. After 30 minutes, uncover the dough and punch it down. - If the dough is too sticky, add small amounts of flour until it reaches the desired texture. If it's too dry, add more warm water. The dough should be soft and elastic, but not sticky.

Shape the dough - Divide the dough into 4 portions. On a floured surface, roll out each portion with a rolling pin until it is about 1/4 inch thick. Make sure the thickness is uniform to ensure even cooking. With a knife, cut the dough into circle shapes. Traditionally, they are about 4-6 inches in diameter. Use a fork to prick the dough all over to prevent it from puffing up while frying. - If you don't have a rolling pin, you can use a clean wine bottle. Make sure the dough is floured and doesn't stick to your work surface. Don't discard the leftover dough scraps - you can roll them up, fry them, and sprinkle them with cinnamon sugar for a sweet treat!

Fry the Lángos - In a frying pan, heat enough vegetable oil to cover the Lángos entirely. Once the oil is hot, slide the Lángos into the frying pan, one at a time. Fry each side until it is golden brown, then use a slotted spoon to remove it from the oil and place it on a plate lined with paper towels to drain excess oil. - Make sure the oil is hot enough - the Lángos should sizzle immediately when dropped in. Don't overcrowd the pan to prevent the Lángos from sticking together. You can also use a deep fryer if you have one.

Serve the Lángos - While the Lángos is still hot, spread a generous amount of sour cream on top of each piece. Sprinkle grated cheese, chopped garlic or your preferred toppings on top of the sour cream. Enjoy while it's still hot and crispy! - Be creative with your toppings! You can use cooked and crumbled bacon, diced tomatoes, sliced onions, or any of your favorite vegetables. If you want a sweeter version, sprinkle some cinnamon sugar on top of the Lángos instead of salt and grated cheese.
