Ingredients

Serves 4

Pithivier

800g Onions, peeled and thinly sliced
3tbsp Rapeseed oil
2kg Maris piper potatoes, peeled, thinly sliced lengthways
Small bunch thyme, leaves picked
100g Melted butter
2 Cloves garlic, crushed
1 Egg, beaten
500g Puff pastry rolled out to 5mm thickness
300g Comté finely grated
200g Spinach leaves, washed
15g Fresh black Truffle

For the Pithivier

  • In large, deep saucepan over a low-medium heat, add the rapeseed oil and slowly cook down the onion slices under a lid until softened but not coloured 20-30 mins, stirring regularly, Season with salt and pepper
  • Remove from pan and set to one side to cool
  • Potato terrine, preheat the oven to 150C. Grease a 400x 300 x 100mm oven proof baking dish, casserole or roasting tin and line it with baking parchment
  • In a large bowl mix the potato slices with the confit onion, picked thyme, melted butter and crushed garlic
  • Arrange the thin slices of potato in overlapping layers in your baking dish, seasoning each layer with salt and pepper as you go, until it is around 8cm deep
  • Top with another piece of baking parchment and put a heavy tray on top to weigh it down. Cook at 150C for 1.5 hours (check after 40 minutes) or until it’s fully cooked and you feel no resistance when you insert a skewer or pointed knife
  • Allow to cool with the weight still on
  • When cool, add an additional weight and move to the fridge for at least 4 hours or ideally overnight
  • Use a 7cm cooking ring to cut out 4 rounds of potato terrine. Use a sharp knife to cut each round in half horizontally, so you have 8 discs in total
  • Blanch the spinach in boiling salted water for 2mins.
  • Drain and plunge immediately into iced water, once cold
  • Drain and lay out the blanched leaves on a clean tea towel

Assembling the Pithivier

  • Place double layer of cling film onto the work surface, brush with a little rapeseed oil
  • Arrange a layer of spinach, followed by one disc of potato, then a generous shaving of truffle, some finely grated Cômté cheese and some more spinach
  • Wrap in the cling film tightly to create a firm cylinder and chill in the fridge for 30 minutes
  • Roll out your puff pastry and cut out two 9cm circles
  • Brush beaten egg on one circle to be the bottom of the pithivier
  • Remove the cling film from the potato cylinder and place on top
  • Lift the second circle of puff pastry to cover the cylinder, press down the edges to seal then return to the fridge to firm up for 15 minutes
  • Repeat until you have four pithiviers in the fridge
  • Egg wash the top of the pithivier generously,
  • Score with the back of a knife, being careful not to cut through the pastry (the classic design is curved lines from the middle of the top disc and down to the edge, as pictured)
  • Place into the fridge until ready to cook
  • Place the finished pithiviers onto a flat baking tray, lined with greaseproof paper, into a preheated oven at 190C for 25 minutes until golden brown
