Whether it is home made pastry or store bought, the crisp and flakiness of the layers just go with anything with cheese. To make my leek & mushroom pastry a whole meal, I decided to add some of my favourite ingredients into the mix. I had to have mushrooms, leeks and rice, not to forget, a whole lot of cheese. I braided the pastry and brushed it with an egg wash to give it that beautiful golden design.
