Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Gently warm the tahini with the vanilla and keep it fluid at about 40C.
Cook the sugar, water, and lemon juice to the hard-crack stage at 150C.
Stream the hot syrup into the tahini while beating steadily.
Continue beating as the mixture thickens and turns fibrous, then fold in the pistachios.
Press into a lined tin and let it cool until completely firm.
Cut into small squares and store in an airtight container.
