For the pastry straws, place the pastry onto a baking sheet, prick all over with a fork and bake in the oven for five minutes.

Remove from the oven, dust with icing sugar and cut into straws or long triangles.
For the rhubarb ketchup, place all the ketchup ingredients into a small pan and cook over a medium heat for 6-8 minutes, or until softened. Pour into a small bowl and leave to cool.
