Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Whisk the cornflour into the cold water until smooth.
Heat the milk with the sugar and mastic until steaming.
Whisk in the cornflour slurry and stir constantly over medium heat until thick, glossy, and stretchy.
Off the heat, stir in the rose water.
Rinse small molds or glasses with cold water, pour in the pudding, and chill for 3 hours.
Turn out or serve in the glasses, topped with chopped pistachios.
