The Middle eastern baklava is usually sweet. This savoury version is perfect for a formal meal. It can also be made ahead and frozen. To freeze, prepare as far as step 11 cool and freeze. Once frozen remove from tins and wrap in foil for up to 3 months. To cook, place whole pie (foil and all) in a 190C oven for 20 minutes and unwrap for a further 10 minutes.
