Churros

1. In a medium saucepan combine the water, oil, and sugar over medium-high heat, and bring to a boil
2. Remove from the heat and add the flour to the water mixture all at once
3. Stir until it forms a ball of dough
4. Allow the dough to cool for 15-20 minutes
5. Transfer the dough into a piping bag fitted with a large star tip
6. Preheat a deep fryer or heavy-bottomed pan filled with vegetable oil to 190C /375F (you can test this by dropping a small piece of dough into the oil, if it bubbles and floats the oil is ready to be used)
7. Combine the sugar and cinnamon in a shallow bowl and set aside until the churros are fried

1. Cut 10 x 10cm square sheets of parchment paper and pipe a heart shape onto each of the pieces

3. Transfer the cooked churros onto a paper towel or wire rack to drain
4. Repeat until all the churros have been fried then toss in the cinnamon sugar

To fry regular churros

1. Pipe 4cm/10inch pieces of dough into the preheated pot of oil (you can cut the dough with a pair of scissors to help drop it into the pot of oil)
2. Fry 2-3 churros at a time, for 2-3 minutes, or until golden brown
3. Transfer the cooked churros onto a paper towel or wire rack to drain
4. Repeat until all the churros have been fried then toss in the cinnamon sugar
