In a bowl, combine flour and salt.

Set the flour mixture aside.

In a large saucepan, bring water to a full rolling boil.

Remove the saucepan from the heat.

Add the flour mixture to the boiling water.

Stir until the mixture is well blended.

Let the dough cool for 5 minutes.

While the dough cools, fit a pastry bag with a medium-size star tip.

Alternatively, use a cookie press fitted with a star-shaped attachment.

Place the cooled dough into the pastry bag.

Squeeze 6-inch lengths of dough onto a large sheet of wax paper.

In a large, deep skillet, heat oil over medium-high heat.

Carefully add half of the dough strips to the hot oil.

Cook for 5 minutes, or until the churros are golden brown, turning occasionally to ensure even cooking.

Remove the cooked churros from the oil and drain on paper towels to remove excess oil.

Repeat the cooking process with the remaining dough strips.

Place the cooked churros on a serving platter.

Sprinkle the churros evenly with cinnamon sugar.

Serve the churros warm and enjoy!
