Mix the flour, sugar and salt in a bowl. Add the butter and rub together using your hands to form an even, crumbly mixture. Add the egg, mix quickly to form a soft dough – do not knead. Flatten the dough, cover and chill for approx. 30 mins.
On a lightly floured surface, roll out the dough into a circle approx. 3 mm thick, transfer to a baking tray lined with baking paper.
Sprinkle the almonds over the dough, leaving a border of approx. 4 cm. all the way around. Mix the strawberries with the sugar, spread on top of the almonds.
To shape & bake
Fold the edges of the dough in towards the middle, press down gently. Brush the edges with egg yolk and sprinkle with the flaked almonds.
Bake: approx. 35 mins. in the centre of an oven preheated to 200°C.
