First, add water and butter to this pot and bring to a boil.
Then add the flour and toast it. Meanwhile, make the syrup, bring it to a boil, and let it cool.
Transfer the cooled dough to a food processor and add 2 eggs, cornstarch, sugar, and semolina, then knead in the food processor.
Next, pour vegetable oil into a pot, place the dough in a piping bag, and use a piping tip to cut the dessert into the cold oil.
Once all the dough has been piped, turn on the stove. Place the cooked dessert in the cold syrup; letting it sit in the syrup for 3–4 minutes is sufficient.
