Heat the oven to 200 °C (400 °F). Make the pastry in the usual way, roll out thinly and use to line a greased 18cm flan ring. Spread the flaked crabe meat over the base of the pastry case and sprinkle with chopped fennel leaves. Lightly whisk together the milk, cream, eggs, a few drops of anchovy essence, salt, pepper and tomato puree. Pour this mixture over the crab and fennel. Bake in the centre of the oven for 15 minutes. Reduce the heat to 180 °C (350 °F) for further 25 minutes (or until the quiche is golden and set).
