1Pre-heat oven to 180°C/160°C fan assisted.
2Gently roll the shortcrust pastry out over a 20cm loose-bottomed quiche tin. Press pastry into the tin and then trim away excess pastry. Chill in the freezer for about 10 minutes.
3In a large bowl or jug, whisk together eggs, milk, sour cream and a generous pinch of salt and pepper.
4Slice goat’s cheese then cut each slice into quarters.
5Pour egg mixture into chilled pastry then evenly distribute the goat’s cheese and halved blackberries. Sprinkle with thyme leaves.
6Carefully transfer to the preheated oven and bake for 30-35 minutes, until quiche is set around the edges and has lost its glossy top but there’s a slight wiggle in the centre.
7Leave to cool for about 15 minutes before enjoying warm. Can also be served cold.
