  • Season
  • While the Jus is reducing add the peas, butter, cream, milk into a pot and season. Set aside for cooking
  • To peal the onions, place them in boiling water for 1 minute. When removed they should be easy to peel. Place the onions into a pot along with 50 g of honey and one tablespoon of butter. Set aside with the pea puree
  • Cut the lettuce into fine strips and chop the bacon. Mix with the bacon and set aside.
  • This should take roughly 25 minutes and by now the stock in the pan will have dissolved if the potato is not cooked add more water.
  • Blanch 50g of broad beans in boiling water for 4 minutes. Refresh in cold water and set aside
  • The carrot should be ready to. This can be checked with the tip of a knife. There should be resistance. Take out of the oven and place aside. Reduce the temp of the oven to gas mark 4 180 degrees Celsius

  • Pace 3 cloves of smoked garlic into a pot with 300 of milk. Salt and pepper. Put on a medium heat and cook until the garlic has softened.
  • The fondant potato should now be cooked and covered on a plate
  • Place the peas onto a medium heat and cook for 4 minutes. Blitz with a blender and pass through a sieve. Put into a squeeze bottle for use after.
  • When the garlic has softened blend and sieve the garlic and milk. Season and add the soy lecithin.
  • The lamb will now be cooked and must be removed covered with foil and allowed to rest.
  • Take the onions and add them to the heat. Cook on a medium heat for four minutes.
  • When cooked leave aside in the bubbling honey and butter mix.
  • It is now time to plate up. Elements need to be heated through on the pan.
  • Add the lettuce and bacon with a teaspoon of butter and dash of oil.
  • In the same pan add the carrots and coat with the same butter mixture.
  • Also heat the fondant and do the same.
  • Place the pan containing the jus over the heat and bring to a simmer.
  • To plate:
  • Place the lettuce and bacon in the centre of a large circular plate.
  • Around the edges place a circle of pea puree. Do this 5 times
  • At the edge of the circle of puree sit one of the baby onions and on the other side stand a small triangle of carrot.
  • Finally carve the lamb, it should be medium rare. Open this out so the pink centres are facing upwards.
  • Add the broad beans into the jus.
  • Spoon a small amount of jus around the lamb. Not on it.
  • Finally blitz the garlic mixture with a hand blender. This will create a foam. Drizzle over the edge of the lamb and serve.
