Method

1
You'll need a long run-up for the lamb so start two days in advance by making the marinade. Combine the water, pink salt, salt and sugar in a bowl. Put the marinade and lamb into a vacuum bag, seal and leave in the fridge for 48 hours
  • 1000ml of water
  • 1 pinch of pink salt
  • 1/2 tsp salt
  • 1 tsp caster sugar
  • 1 lamb belly
2
The next day, while the lamb is still in the fridge, prepare the lamb jus. Preheat the oven to 195°C/Gas mark 5. If your oven has a convection setting, select it
3
Roast the bones in the oven until golden brown
  • 3kg lamb bones
4
While the bones are roasting, make a mirepoix by chopping the onion, garlic and thyme
  • 1 onion
  • 1 bulb of garlic
  • 1 bunch of fresh thyme
5
When the bones are golden, add the mirepoix, lower the oven temperature to 165°C/Gas mark 3 and roast for 10 minutes
6
Add enough water to cover the bones, turn off the convection setting (if you have one) and bake for 3 hours
7
Strain the bones, reserving the golden/light brown liquid. Lift the fat off the top and reduce the stock until it has a strong flavour. Leave in the fridge overnight to set
8
Take the vacuum bag with the marinated lamb from the fridge, place into the sous vide bath and cook at 65°C for 12 hours
9
On the day you plan to serve the dish, start by making the onion leaves. Vacuum seal the pearl onions at full pressure, microwave for 1 minute and then place the bag in ice-cold water
  • 8 pearl onions
10
When the onions are cold, cut through the equator and peel off the leaves for garnish
11
Sweat the shallots in a saucepan with the butter and oil. While they are cooking, toast the amaranth grain in a separate pan and then add to the shallots. Cover with the chicken stock. Allow to cook for 10-12 minutes, the grains should still have a little crunch. Season and reserve somewhere warm until ready to plate
  • 30g of shallots
  • 10g of butter
  • 1 tbsp of olive oil
  • 100g of amaranth grain
  • 250ml of white chicken stock
  • salt
  • pepper
12
To make the milk skin, fill a half gastro tray 4cm deep with the milk, put it on top of the stove and bring to 110°C (use a thermometer to keep the temperature constant) so a skin will form
  • 400ml of whole milk
13
Carefully lift the skin off onto a tray lined with cling film and sprinkled with a few drops of milk to stop the skin sticking. Add more drops of milk and more cling film, wait for the next skin to form, and repeat
  • 600ml of whole milk
14
Take the lamb belly out of the vacuum bag and cut into portions, (this is easier when it's cold) then lightly colour all sides in a pan to reheat. While the lamb is cooking, reheat the jus also.
15
To plate, place a spoonful of amaranth in the centre of the plate. Arrange the lamb belly next to it. Scatter the onion leaves across the amaranth then top with the milk skin. Drizzle the jus across the plate, then scatter the samphire, tahoon cress and wood sorrel to garnish
  • 1 handful of samphire
  • 1 handful of tahoon cress
  • 1 handful of wood sorrel
