60 g butter - melted in microwave
80 g grated parmesan
60 g plain flour
1 teaspoon chopped fresh rosemary
Melt butter in microwave then add the rest of the ingredients and combine until the mixture forms a dough. It will probably be quite crumbly but firm it up with your hands and pop in the fridge for an hour. Roll out and cut (or press by hand) into small cracker shapes. Pop into a pre-heated oven (mine is fan) at 160 and cook for 8 to 10 minutes until browning at the edges.
Try not to eat them all at once!
