Fish and Egg Tartlets

For the pastry: put the flour in a mixing bowl and stir in the salt. Rub in the butter with your fingers until the mixture resembles breadcrumbs. Stir in the egg and mix with your hands to form a dough. If the mixture is too dry, add a little water, if it is too wet add a little more flour. Shape into a ball. Wrap in cling film and chill for 30 minutes.

Heat the oven to 200°C (180° fan) 400°F gas 6. Brush 4 mini tart or quiche tins with oil or melted butter.

Divide the dough into 4 equal portions. Roll out 1 piece of dough on a floured surface until it is larger than the diameter of the tin.

Gently roll the pastry around the rolling pin. Unroll the pastry on top of the tart tin, then use your hands to lower the pastry into the corners of the tin, pressing it into the edges. Repeat with the remaining portions of dough.

Prick the bases of the pastry cases with a fork and bake for about 10 minutes until golden. Remove from the oven.

Reduce the oven temperature to 180°C (160° fan) 350°F gas 4.

For the filling: heat the butter in a frying pan and cook the leeks for about 8 minutes until tender. Remove from the heat and leave to cool.

Whisk the eggs with the creme fraiche until smooth. Stir in the salmon and leeks and season to taste with salt and pepper.
