Roll out puff pastry leftovers. Dock and brush with clairified butter. Sprinkle a little salt, herbs and gently press cheese onto its surface. Using a very sharp knife or pizza wheel, cut equal strips and taking both ends, twist, ever so gently and place onto parchment lined sheet pan. Press the ends down firmly. Bake in very hot oven and they puff up beautifully. What a satisfying crunch. Eat them as is or dip into something tasty.
