The Cook’s Mind

What This Recipe Helps You Practise

• Making a duxelles of finely chopped mushrooms.
• Balancing flavours with herbs and seasoning.
• Working with puff pastry for a crisp finish.
• Timing the bake so filling and pastry finish together.

Make-Ahead

• Can be assembled ahead and baked when ready.
• Keeps well if baked earlier and reheated gently.

Freezer-Friendly

• Pastry loses some crispness when frozen.
• Filling can be frozen separately and assembled fresh.
• Key Substitutions
• Mushrooms: use chestnut or portobello for depth.
• Pastry: use shortcrust if puff is unavailable.

Cooking Parlance

• Duxelles: finely chopped mushrooms cooked down to a paste.

Ingredients

  

1x2x3x

• 100 g Puy lentils | dried weight

Ingredients for the Wellington middle

• 250 g brown onion | unpeeled weight – small dice chop
• 1 clove fresh garlic
• 10 ml olive oil
• 1 pinch salt
• 100 g cashew nuts | chopped into small pieces
• 250 g chestnut mushrooms | chopped into small pieces
• 2.5 ml red wine vinegar
• 1 pinch dried thyme
• 1 pinch dried rosemary
• 15 ml light soy sauce
• 5 ml gravy browning
• salt | to taste
• ground black pepper | to taste

Other ingredients

• 320 g puff pastry
• 10 ml soya milk | unsweetened
• 10 ml olive oil

Instructions

 

• Bring a pan of water to the boil and add the lentils. Gently for 10+ minutes to cook until there is a little bite to them.
  100 g Puy lentils

Prepare the Wellington middle

• Peel and small dice chop the onion.
  250 g brown onion
• Peel and small dice chop the garlic.
  1 clove fresh garlic
• Heat a large frying pan on a medium low heat, add the oil and wait for it to heat through. Then sweat the onion and garlic slowly with a good pinch of salt.
  10 ml olive oil, 1 pinch salt
• At the same time, put the cashews into the Magimix to break into smaller pieces.
  100 g cashew nuts
• Add mushrooms to the Magimix to chop.
  250 g chestnut mushrooms
• When the onion and garlic are nicely caramelised, deglaze the pan with the vinegar.
  2.5 ml red wine vinegar
• Add the cashews and mushrooms and continue to cook, to reduce down. You need the water inside the mushrooms to evaporate.
• Add the rest of the ingredients: thyme, rosemary, soy sauce, gravy browning.

  Mix and then add the cooked lentils.
  1 pinch dried thyme, 1 pinch dried rosemary, 15 ml light soy sauce, 5 ml gravy browning
• Taste and season the mix.

  Leave to cool. The mix needs to be properly cold.
  salt, ground black pepper

Fill the pastry

• Preheat the oven to 180℃ fan (200℃ conventional).
• Unroll the pastry, fill the middle and close up the edges.
  320 g puff pastry
• Turn over so the seam is at the bottom. Using a very sharp knife, create slits in the top of the puff pastry. Mix together the soya milk and olive oil. Brush the top of the puff pastry with mixture.
  10 ml soya milk, 10 ml olive oil
• Cook in the oven for 40-60 minutes – until golden; keep on with the cooking until it’s properly brown and looks well cooked and crispy golden. I turned mine around halfway through because it was going a deeper colour on one end (in an oven hot spot).

Notes

• Multi-purpose: use the filling for making pasties or take slices for lunches with salad. It’s great for Sundays and Christmas.
• Make-ahead: you could make the filling and hold in the fridge; then simply roll into the pastry and bake.
