Ingredients:

  • 2 Fillets of firm white fish (approximately 200g each)
  • 1 tbsp Olive oil

 

White Wine Emulsion

  • 1 Shallot, peeled & diced
  • 1 Sprig of thyme
  • 1 tbsp Olive oil
  • 125ml White wine
  • 250ml Fish stock
  • 125ml Double cream
  • 100ml Full fat milk

 

Garlic Potato Puree

  • 350g Starchy potatoes, peeled and diced
  • 200ml Double cream
  • 25g Butter
  • 2 Cloves of garlic, peeled

 

Potato Crisps

  • 1 Small potato, peeled & finely sliced using a mandolin or potato peeler
  • Frying oil

 

To Serve

  • 4 Asparagus spears, blanched & halved lengthways
  • 8g Black truffle, finely sliced
  • Parsley cress or small parsley leaves

Directions:

White Wine Emulsion

  1. In a suitable pan gently pour in the olive oil & gently sauté the shallots & thyme.
  2. Add the wine to the pan and simmer to reduce by half.
  3. Once the wine has reduced add the stock and reduce by a half.
  4. Finely add the cream and reduce again by half.
  5. Pass through a sieve and reserve the liquid.
  6. When ready to serve, bring to the boil and then add the cold milk.
  7. Using the blending shaft, emulsify. This is done by allowing the blade to whisk just on the surface of the liquid, allowing bubbles to form on top.

 

Garlic Potato Puree

  1. Gently boil the potatoes for 15-20 minutes until soft and drain.
  2. Place the garlic in a pan of water and bring to the boil. Drain and repeat once more.
  3. Add the boiled garlic to the cream and bring to a simmer.
  4. Add the garlic and cream to the drained potatoes. Using the potato masher, process until smooth.

 

Potato Crisps

  1. Rinse the potatoes several times in clean water to wash away the starch and dry off.
  2. Heat a deep pan with oil until the oil is 170ºC (use a thermometer to test).
  3. In batches, fry the potato slices until golden & crisp (approximately 1-2 minutes).
  4. Lightly salt and allow to drain on a paper towel.

 

Fish

  1. Preheat the oven to 180ºC.
  2. Pour the olive oil into a suitable pan and fry the fish fillets skin side down until the skin becomes crispy.
  3. Bake in the oven for a further 6 minutes.

 

To Serve

  1. Spoon the garlic potato puree onto each plate, followed by placing a roasted fish fillet on top.
  2. Scatter the potato crisps over the potato puree.
  3. Garnish with the asparagus, sliced truffle and parsley cress.
  4. Spoon over the white wine emulsion and serve.
