Slow Cooked Lamb Ribs on Truffle Puree and Letils

Let's prepare it!

Lentil Stew method Rinse the lentils well and set them in a wide bowl. Cover with water and soak for at least 12 hours or overnight with baking soda powder.
Place the onions, carrots, and celery in a large saucepan or soup pot with two tablespoons of olive oil and sauté gently on low heat until the vegetables are very softened and the onions are somehow translucent, but not coloured. 
Add bay leaf, drained lentils and chicken stock. 
Add the remaining ingredients, bring to boil and then turn the heat down to a gentle simmer and cook until the lentils are tender, for about 45 min.
Keep checking on them and add more water if necessary. 
Only when the lentils are tender, add salt to taste, otherwise, they will remain hard. 
Lamb ribs marination base process Drain out the blood and trim the excess fat from the upper part of the lamb's ribs.
Incorporate all ingredients together and marinate the lamb overnight.
Cook sous vide at 82.2* for 9 hours.
Cool in ice cold water.
Open the vacuum bag and organize a la carte portion size.
Strain and simmer the sauce.
Skim out the fat that comes to the surface and reduce the sauce by 2/3 or until became thickened. 
Cool it and add to the pre-portioned lamb rack in the vacuum bag and keep in mise en place until needed.
Finalize dish Warm the lamb ribs and the lentil stew in different pots, adding a little chicken stock.
Using a siphon pour the truffle espuma on the plate.
Lay the ribs on the plate and top them with lentils.
Grate black truffle and finalize with some micro herbs, extra virgin olive oil and lamb jus.
