In a food processor, blitz the Parmesan and picked herb leaves till fine, then add to the flours, the butter and lemon zest.
Slowly mix. It will go through a breadcrumb stage then suddenly clump together.
Divide in two to make it easier to work with, roll out to approx 5mm thickness then cut your shapes.
Arrange on a lined baking tray, and bake at 160c in a fan oven for 10-12 minutes for the sticks, a little longer if you make biscuit rounds.
Serve alongside a drink or in a cheeseboard, delicious.
