25g/1oz parmesan, finely grated (or alternative vegetarian hard cheese)
handful fresh thyme, chopped
150g/5½oz Blue cheese, we used Stilton, crumbled
salt and freshly ground black pepper
*You can also make this crust free.
Make the gluten free pastry according to the recipe, then preheat the oven to 180C/350F/Gas 4.
Roll the gluten free pastry out between two sheets of cling film, remove the cling film and use the pastry to line a 25cm/10in tart tin.
Line the pastry with greaseproof paper, fill with baking beans and bake for 10-15 minutes. Remove the baking beans and greaseproof paper and bake for a further five minutes, or until pale golden-brown.
Meanwhile, for the filling, wilt the spinach in a saucepan with a little water. Set aside to cool, then squeeze out the excess water and chop finely.
Cook the potatoes in boiling water for 10 minutes, or until just cooked, then cool and slice into 0.5cm/¼in slices.
Whisk the eggs in a bowl, then whisk in the lactose free cream, lemon zest, nutmeg, cayenne and parmesan. Season well with salt and freshly ground black pepper, then stir in the spinach and half of the thyme.
Arrange the potato slices in the bottom of the pastry case and sprinkle over the Stilton. Spoon in the spinach mixture and sprinkle over the remaining thyme.
Bake in the oven for 35-40 minutes, or until golden-brown and just set. Remove from the oven and set aside to cool for 10 minutes.
