For the shortcrust pastry:
- 200 g plain flour
- 100 g chilled butter, diced
- pinch of salt
- 1 egg, beaten
For the filling:
- 250 g baby or destalked large spinach leaves
- 7 baby new potatoes (unpeeled)
- 4 eggs
- 250 ml double cream
- salt and freshly ground black pepper
- zest of 1/2 lemon
- pinch of freshly grated nutmeg
- pinch of cayenne pepper
- 25g parmesan cheese, finely grated
- 150g soft goat’s cheese (sliced from a goat’s cheese log)
- 25cm diameter tart tin
- Make the pastry: place the flour, salt and butter in a food processor and whiz briefly, or rub together to bread-crumb consistency.
- Add half the beaten egg and continue to mix. You might add a little more egg, but not too much as the mixture should be moist enough to come together.
- With your hands, flatten out the ball of dough until it is 2cm thick then wrap in cling film and leave in the fridge for at least 30 minutes.
- Preheat the oven to 180°C (350°F/Gas mark 4). Line the tart tin and ‘bake blind’.
- Wash and spin the spinach, removing any tough stalks and stems if using large spinach leaves. In a medium-sized saucepan, cook the spinach in just the water that’s clinging to it over a low heat until it wilts. Drain in a colander or sieve and allow to cool a little, then squeeze most of the moisture out with your hands and chop roughly.
- Meanwhile, steam or boil the potatoes until just cooked, and cool on a tray or board. When cool enough to handle, cut into 5mm (1/4 in) slices.
- In a medium-sized bowl, whisk the eggs and add the cream, salt and pepper, lemon zest, nutmeg, cayenne pepper and Parmesan. Whisk these ingredients together then add the spinach and mix through.
- Season well; potatoes are very mild and need a good contrast.
- Spread the potato slices over the base of the prepared tart, and dot with the goat’s cheese
- Gently spoon over the spinach cream mixture as high as you can go. If you are concerned about spillage, carry the tart minus the last few spoons of filling over to the oven.
- Place in the oven, spoon over the remaining filling and any remaining potato and cheese slices. Bake for 35–40 minutes until the tart is golden brown and just set in the centre. Remove from the oven and allow to cool for about 10 minutes before serving.
