½ teaspoon paprika, plus extra for sprinkling over
Method
Preheat the oven to 200°C/400°C/gas mark 6.
Line two baking sheets with greaseproof paper and set aside.
Cut the butter into small cubes, then place in a bowl. Add the flour and rub together until it resembles breadcrumbs.
Finely grate the Parmesan, then add 60g to the flour and butter, along with the mustard and paprika. Stir in 1 to 2 tablespoons of cold water until the mixture comes together.
Roll it out on a floured surface, forming a rectangle about 1cm thick. Slice it into 1cm sticks and place onto the baking sheets.
Sprinkle over the remaining cheese, a little more paprika and bake for 15 to 20 minutes, until golden.
