Dehydrator
Sous vide equipment

To prepare the duck hearts, clean with a J-cloth to remove the thin outer skin. Dissolve the salts and sugar in the water to make a brine, add the garlic, thyme and pepper then add the hearts. Set aside in the brine for 4 hours

8 duck hearts
1 pinch of pink salt
1 tsp salt
2 tsp caster sugar
1000ml of water
1 bulb of garlic
1 pinch of thyme
pepper

Once the hearts are brined, drain well, place in a plastic vacuum bag and sous vide for 3 hours at 48°C

Place the cleaned tongues in a vacuum bag with the duck fat and sous vide for 4 hours at 85°C. Once cooked, remove the small bones from the tongues

4 duck tongues
2 tbsp of duck fat

Soak the morel mushrooms in water for 30 minutes, then drain on some kitchen paper

4 morel mushrooms

Remove the enoki tops from the stems (the tops can be reserved for other dishes), shred the stems and place in a dehydrator for 1 hour at 55°C. Alternatively, spread on a baking parchment-lined baking sheet and dry in the oven at a very low heat for an hour

1 clump of enoki mushroom, small

Meanwhile, prepare the spiced broth. Gently fry the garlic in a pan with 1 tablespoon of the olive oil. Once golden brown, remove and drain on kitchen paper. Repeat with the ginger and the other tablespoon of oil

1 tbsp of garlic, finely chopped
2 tbsp of olive oil
1 tbsp of root ginger, finely chopped

Add a dash of oil to a pan and cook the chopped onion until golden brown. Remove the cooked onion and add the duck leg meat to the same pan. Cook through, then add the diced apple, cinammon stick and star anise

2 tbsp of onion, finely chopped
2 duck legs
1 apple, diced
1 cinnamon stick
1 star anise

Add the water and chicken stock and reduce by half. Strain, return to the heat and add the garlic and ginger. Reduce by half again and add the rice vinegar

500ml of water
250ml of chicken stock
1 tbsp of rice wine vinegar

Add the olive oil to a pan and sauté the morels. Clean the St George mushrooms with a wet cloth and slice as you would a truffle

1 tsp olive oil
4 St George mushrooms

Cut the duck hearts in half lengthways and sauté them in a little butter

1 knob of butter

To plate, divide the duck hearts and tongues into bowls. Scatter over the mushrooms, pour over a generous serving of the spiced broth and and top with the dehydrated enoki stems. Serve immediately
