Leek, Fennel & Olive Tart recipe

A scattering of olives and anchovies adds deep savoury flavours to this seasonal tart.
Don’t forget to use almost all of a leek; remove the tougher dark green leaves at the end. There is quite a bit in the middle that should not be discarded - just give it a good clean first.
