Similar thing may do:
make up a pastry case - mix the basic pastry:
8oz self raising flour
4oz margarine
1oz milk
2oz caster sugar
and bake this blind at 190 C
Meanwhile make up the filling:
4oz margarine
3oz plain flour
6oz golden syrup
12oz warm milk
Melt the margarine and stir in flour. When mixed stir in the warm milk and stir until it thickens. Remove from heat and
cool. Add golden syrup, then pour the sticky mixture into the pastry case and allow to set.
Show off and top with choc vermicelli, choc curls or shavings, fresh raspberries steeped in strawberry liqueur, or mascarpone with lemon zest, cinnamon sugar dusting, etc etc
Or just cream whipped to soft peaks...
