Step 1

Preheat the oven to 170°C/fan150°C/gas 3½.

Step 2

Melt a knob of butter in a frying pan, then add 2 sliced leeks and cook over a medium heat until softened and golden. Season, then arrange the leeks in a 23cm blind-baked tart case (see our video below) and scatter over 100g crumbled feta.

Step 3

In a jug, mix together 200ml double cream, 100ml whole milk, 2 large free-range eggs and 2 large free-range egg yolks. Season, then pour into the case.

Step 4

Bake in the oven for 25-30 minutes until set with a slight wobble. Allow to cool for 15 minutes, then serve.
