Mix the flour, rosemary and salt in a bowl. Add the butter and rub together using your hands to form an even, crumbly mixture. Pour in the water and mix quickly to form a soft dough; do not knead. Flatten the dough, cover and chill for approx. 30 mins. Divide the dough into 4 portions. On a lightly floured surface, roll out into ovals approx. 2 mm thick. Place on a baking tray lined with baking paper.
Approx. 15 mins. in the centre of an oven preheated to 200°C. Remove from the oven, leave to cool completely on a rack.
Drizzle with the nut spread, sprinkle the berries, pistachios and fleur de sel on top.
