Combine the flour, sugar and salt into a bowl.
Grate the cold butter over it. Rub in to represent bread crumbs.
Add enough cold water to bring the dough together, no need to knead.
Cover with a cling film and refrigerator for an hour.
Preheat oven to 200 degrees. Keep a tray with parchment/ silicon mat ready.
On a lightly floured surface, flatten the dough into a big round which is 1/4 inch thick. Carefully transfer to the tray.
Hull and chop the strawberries. Mix with the sugar, lemon juice and vanilla.
Put it in the center of the round leaving around 3 inches around. Fold the sides inwards. Sprinkle the almonds on top. Brush milk on the pastry side.
Bake for around 40 minutes or till the strawberry bubbles.
Serve with icing sugar or whipped cream.
