Chocolate churros with chocolate & salted caramel sauce

To make the sauce, tip the sugar and butter into a saucepan and bring to a simmer until the sugar has melted, then stir in the cream and simmer until you have a smooth sauce, about 2-3 mins. Remove from the heat, stir through a pinch of sea salt and the chocolate, and continue to stir for 2-3 mins, or until it has completely melted. Keep warm or leave to cool for reheating later. For the coating, mix the sugar with the cinnamon and a small pinch of fine sea salt and set aside.

For the churros, tip the flour, cocoa, baking powder and a large pinch of salt into a bowl. Add the vanilla extract and melted butter, then carefully pour in 250-300ml boiling water and whisk to make a smooth, very thick batter. Leave to cool for a few minutes, then scrape the mixture into a piping bag fitted with a medium star nozzle.
