- In a sauce pan on medium heat, add water, sugar, vegetable oil, and salt.  
- Continue stirring until the sugar melts and the mix is well incorporated.  
- Once the water comes to a boil, turn off the heat.  
- Add the flour and mix until a pastry dough forms.  
- Let it sit aside to cool down.  
- Mix the sugar and cinnamon and set aside as a rolling station.  
- Place your cooled pastry into pastry bags. If you have tips, choose wide ones if not, don't stress I usually make them with no designs and do not use pastry tips.  
- In a pan heat oil for deep-frying, and add the churros without over crowding the pan.  
- Fry in batches until golden and roll in sugar/cinnamon as soon as you take them out of the oil so the sugar sticks.  
- Serve hot and enjoy.
