Bring the water to a boil in a pot and add the butter and salt.

Once melted, remove from heat and add the flour, stirring vigorously until a smooth dough forms.

Let cool slightly, then add the eggs one at a time, mixing until the dough is smooth and elastic.

Heat oil in a deep pan to 180 degrees Celsius.

Using a spoon, drop small portions of the dough into the hot oil.

Fry until golden brown, then drain on paper towels and serve warm.
