Serves: 4 as a starter
Preparation time: 40 minutes, plus resting the pastry
Cooking time: 25-30 minutes
For the pastry:
- 100g cold butter, cut into 1cm dice
- 200g plain flour
- 8 sage leaves, finely chopped
- 25g parmesan, finely grated
- Pinch salt
For the filling:
- 2 whole bunches of celery, remove outer leaves and trim roots but do not separate out the sticks
- 50g unsalted butter
- 1tbsp olive oil
- 1tbsp dark brown sugar
- 1tbsp balsamic vinegar
- Salt & freshly ground black pepper
- 25g freshly grated parmesan to sprinkle
What to do:
Pre-heat the oven to 180°C.
Make the pastry in a large bowl by tossing the diced butter in the flour, sage, parmesan and a pinch of salt. Add just enough ice-cold water, about 6-8 tablespoons, to bring it together into a firm dough that is not too sticky. There should be no loose pieces of fat or flour left in the bowl.
Turn onto a floured work surface and roll into a rectangle of about 1 cm thick. Fold the top third into towards you into the middle, and the bottom third up over it – just like folding a letter. Turn the pastry by 90°, roll out to a rectangle again and repeat the folding. Repeat this turning, rolling and folding process 4 or 5 times, keeping the board and rolling pin lightly floured. Wrap the pastry in cling film and chill for at least an hour before using.
Whilst the pastry is chilling, make the filling. Cut each celery bunch into half through the root, then each half into quarters leaving you with 8 pieces. Melt the butter with the oil in a frying pan that can go in the oven. Add the sugar, balsamic vinegar and celery and season with a little salt and freshly ground black pepper. Cover the mix loosely with a piece of damp greaseproof paper and gently sweat for 15-20 minutes until the celery is soft & tender when pierced with the point of a knife.
Remove the greaseproof paper, turn up the heat and fry for a further 5 minutes until lightly caramelized. Turn off the heat and spread the celery out evenly in a single layer over the base of the pan. Allow to cool a little.
On a floured work surface roll out the pastry into a circle just a little larger than the frying pan. Carefully lift the pastry and lay over the celery, tucking the edges under. Bake in the oven for 20 minutes or until the pastry has puffed up. Remove from the oven and carefully turn out onto a baking sheet. Sprinkle with the rest of the parmesan and return to the oven for a further 5-10 minutes until the parmesan has browned and the pastry is cooked through.
Cooks tip: this pastry freezes really well so make a double batch and store the rest for a later date. If you want to prepare ahead, make up to the turning out stage then cool. When ready to serve, sprinkle with the cheese and reheat in a hot oven.
