Put the butter water and salt into a small pot and heat until the butter is just melted. Stir in the flour and mix well to combine. Stir over a low heat for 1 minute. Cool for a couple of minutes.
Add the eggs one at a time mixing well after each addition. The batter will be quite stiff .
.
Spoon the batter into a piping bag with a star tube
Prepare a flat plate with the 200 gm sugar and cinnamon mixed together. This will be to roll the Churros in when they are cooked.
Choose a low sided pot or deep fry pan. Put this on a medium heat. Test the temperature by dropping a small amount of dough into it and check if it bubbles.
When the oil is ready begin to pipe long fingers of dough into the pan only a couple at a time. Cut the length of churros fingers you'd like as they come out of from the piping bag. A pair of scissors or a small knife will make it easier to break them off into fingers.
Fry them , turning till they are golden then remove them with tongs onto draining paper.
Once drained roll them in the cinnamon sugar and put onto a plate
Serve with chocolate sauce
