Sous Vide Lamb Rump with Cauliflower Couscous and Chocolate Jelly (lamb rump)

I cooks lamb rump sous vide and serves it with some elegant accompaniments; including a sweep of cauliflower purée, cauliflower couscous with raisins, caramelised cauliflower florets and an unusual chocolate jelly. Lamb and chocolate may seem a strange combination, but the earthiness of the chocolate balances the muscular flavour of the meat perfectly.

Method

  1. Begin by preparing the chocolate jelly. Heat the chicken stock in a small saucepan until it reaches a simmer, then add the chocolate and whisk to melt. Mix thoroughly and leave to cool.

    • 230g of chicken stock
    • 80g of bitter chocolate, chopped, plus extra for grating

  2. Gently whisk in the agar agar, bring to the boil, while stirring, then pour into a shallow tray. Allow to cool and place in the fridge to set while you prepare the other elements.

    • 3g of agar agar

  3. For the cauliflower purée, melt the butter in a heavy-based saucepan over a medium heat. Add the onion and garlic and cook until soft and golden brown. Add the sliced cauliflower, cook until golden and caramelised, then add the stock. Bring to a simmer and cook until the cauliflower is soft and tender.

    • 50g of butter
    • 1/2 onion, finely sliced
    • 1 garlic clove, finely sliced
    • 1 cauliflower, washed and sliced
    • 200g of chicken stock

  4. Continue to simmer until the stock reduces by half. Add the cream and reduce by half again, remove from the heat and transfer to a blender. Blitz until smooth, pass through a fine strainer and set aside until required.

    • 300g of cream

  5. Preheat a water bath to 58.5˚C

  6. To prepare the lamb, trim off the fat and score the flesh (optional). Seal in either 1 large vac pac bag (making sure the lamb pieces are not overlapping) or 4 small bags, with extra virgin olive oil, thyme and rosemary. Cook in the water bath for 45 minutes.

    • 4 lamb rumps, 225g each
    • 4 sprigs of fresh thyme
    • 4 sprigs of fresh rosemary
    • extra virgin olive oil

  7. Meanwhile, prepare the caramelised cauliflower. Cut the cauliflower into medium-sized florets and blanch in salted boiling water until tender, for approximately 2-3 minutes. Strain and cool in iced water.

    • 1 cauliflower, washed
    • salt

  8. Drain well and set aside. Add the butter to the frying pan and make a very light beurre noisette. Add the florets, caramelise until golden brown and season.

    • 25g of butter
    • salt
    • pepper

  9. To prepare the vinaigrette, simply whisk together the vinegar and oil, season to taste and store in a squeezy bottle until required.

    • 60ml of white wine vinegar, good quality
    • 240ml of extra virgin olive oil
    • salt

  10. For the cauliflower couscous, soak the golden raisins in boiling hot water for 20-30 minutes, strain and set aside. Dice the pancetta into 6mm chunks and finely grate the cauliflower.

    • 100g of golden raisins
    • 30g of pancetta, small dice
    • 1 cauliflower, washed

  11. Place a saucepan over a medium heat and add a small dash of oil. Once the oil is hot, add the pancetta and fry until caramelised. Then, add the grated cauliflower, season to taste and finish with a good pinch of chopped chives. Finally, add a dash of the vinaigrette to taste and the raisins.

    • rapeseed oil
    • 1 pinch of chives
    • salt

  12. Halve the artichokes, spoon out any remaining flesh and season with salt. Sauté in a hot pan with a little extra virgin olive oil until golden.

    • extra virgin olive oil
    • salt
    • 2 baby globe artichokes, cooked

  13. Once the lamb is ready, remove from the water bath and vac pac bag and dry off any excess moisture with kitchen paper. Seal in a hot pan with a small dash of rapeseed oil until golden brown on all sides, remove and place on a board ready to carve.

  14. To serve, slice each rump into 2 pieces and serve onto plates on top of the cauliflower couscous.

  15. To each plate, add a dollop of the purée, caramelised cauliflower florets, chocolate jelly cubes and some sorrel. Drizzle with the jus and serve immediately.

    • 100ml of lamb jus
    • 1 handful of sorrel
