Prepare the filling (check the recipe).
Boil about 100 ml of water and set aside for 3 minutes. In a bowl, place the flour and oil. Gradually add hot water – add the water gradually (1 tablespoon at a time), so as not to add too much and so that the dough is not too sticky. First, mix and knead the dough with a spoon, and then by hand until it is smooth and elastic. Cover the bowl with the finished dough with a cloth and set aside for 10-20 minutes.
After the indicated time, take the dough out onto a lightly floured surface. Roll out the dough thinly (about 2 mm thickness). Cut circles from the dough using a cutter or a glass.
Place a heaping teaspoon of filling in the center of each circle. Moisten the edges of each circle with water and seal with fingers or a cutter.
Arrange the dumplings on a floured board and cover with a cloth to prevent them from drying out before cooking. FREEZING: If you want to freeze the dumplings to eat them another day, immediately after making them, arrange them on a lightly floured board, leaving a small gap between each piece so they don't stick together. Then place the board with the dumplings in the freezer for about 1 hour. After the indicated time, you can transfer the dumplings to a bag or container and put them back in the freezer.
Cook the dumplings (immediately after preparation or frozen) in small batches: in a pot, boil lightly salted water. Adjust the amount of water so that it is about 5 times more than the batch of dumplings being cooked. Put the dumplings into the boiling water and cook for a few minutes after they float to the surface. Then remove them with a slotted spoon.
Eat immediately after preparation or fry after cooling.
