1 Preheat oven to 180C/gas 4. Line the base of a 23cm-diameter cake tin with
baking parchment.
2 In a bowl, cream the butter and sugar together until
white and fluffy. Add the eggs one at a time, stirring in between. Using a
pestle, bash the pistachios up in a mortar, then add them, the ground almonds,
lemon zest and rosewater to the creamed butter mixture. Fold in the flour.
3
Spoon the mixture into the cake tin and bake for 25–30 minutes. Remove when done
and let cool.
4 In a bowl, mix the icing with half the juice and spread this
over the cake when cool, then add some flowers to decorate, and serve.
