Indulge in the sweet and crispy delight of Mexican churros. In a saucepan, combine water, butter, sugar, and salt, and bring it to a boil. Remove from heat and stir in flour until the mixture forms a smooth dough. Transfer the dough to a piping bag and pipe it into hot oil, cutting it into desired lengths. Fry until golden brown and then roll the churros in a mixture of cinnamon and sugar. These delicious treats are perfect for dessert or a sweet snack.
