Gluten Free Cinnamon Churros with Chocolate Sauce

Chocolate sauce: Put the cream and rum in a small saucepan and bring to just below the boil. Take off the heat, add the chocolate and whisk to make a smooth sauce. If making the sauce ahead, rewarm to serve.
Churros: Put the milk, butter and salt in a medium saucepan and slowly bring to the boil to melt the butter. Take off the heat and tip in the flour and cinnamon, beating vigorously with a wooden spoon until a thick dough forms and pulls away from the sides of the saucepan. This will happen quickly. Tip the dough into the bowl of a standing mixer. Add the eggs, one at a time, beating thoroughly between each addition. The dough should be shiny and smooth.
To cook: Fit a pastry bag with a star nozzle and half fill with the dough.
Heat 3cm of vegetable oil in a medium deep sided saucepan to 170˚C or until a cube of bread is golden in 30 seconds.
Pipe lengths of dough directly into the oil but don’t overcrowd the pan as they puff up during cooking.
Cook for 1 minute, turn over and cook for another 1 – 1½ minutes until golden and crisp. Lift out and place on paper towels then roll in the cinnamon sugar. Place on a cooling rack set over a baking tray in a warm oven until all the churros are cooked then devour immediately!
