For the base:
225g/8 oz/2 cups digestive biscuit (Graham cracker) crumbs
25 g/1 oz/2 tbsp caster (superfine) sugar
5 ml/1 tsp ground cinnamon
50 g/2 oz butter or margarine, melted
For the filling:
15 g/1 tbsp powdered gelatine
30 ml/2 tbsp cold water
2 eggs, separated
100 g caster (superfine) sugar
350 g/12 oz full fat soft cheese
Grated rind and juice of 1 lemon
150 ml double (heavy) cream
25g/1 oz chopped mixed nuts
Method:
Stir in the biscuit crumbs, sugar and
cinnamon into the butter or margarine. Press over the base and sides
of a 20 cm/8 in loose-bottomed flan tin (pan). Chill.
To make the filling, dissolve the gelatine in the water in a small
bowl. Stand the bowl in a pan of hot water and stir until the gelatine
dissolves. Remove from the heat and leave to cool slightly. Beat
together the egg yolks and sugar. Stand the bowl over a pan of gently
simmering water and continue to beat until the mixture is thick and
light. Remove from the heat and beat until lukewarm. Fold in the
cheese, lemon rind and juice. Whip the cream until stiff, then fold it
into the mixture with the nuts. Carefully stir in the gelatine. Whisk
the egg whites until stiff, then fold them into the mixture. Spoon
into the base and chill for several hours or overnight before serving.
