to make parmesan crisps you'll need grated Parmesan cheese you could great fresh parmesan but i find the packet grated parmesan easier to work with and actually gives a crispier biscuit and one tablespoon of plain flour in a large bowl place the ingredients and mix them together to combine make sure they're thoroughly mixed now line a baking tray with baking paper and using an egg ring metal or silicon as you guide place the ring on the tray in one of the corner positions then spoon or quantity of the cheese and flour mixture into the center use enough to cover the base of the inside of the ring if you add too much the biscuit will be too thick and not crisp once you've done one lift the egg ring off and move it to the next position and repeat once you've filled the tray place the tray into a moderate oven for 5 to 10 minutes when they immediately come out of the oven they will be soup quite soft and pliable so leave them on the tray until they're completely cold for a lovely crisp biscuit one school they can be used as crackers or as accompaniments for meal
