Method

  1. For the gravy, prep all mirepoix, carrots, celery, onion, bay leaves, pepper corns, giblets and bons if accessible, add to a pan and colour them until almost charred, add the congac and allow to reduce to almost a syrup, top up with stock and allow to boil for about an hour until thickened. Once thickened strain through a chinoux, montange butter in if at a good consistency then season.
  2. For the cumquat marmalade, remove the rind from the cumquats then open and squeeze the juice from them all into the same pan, as well as the squeezed cumquat shells. Add your sugar, water and cognac then allow to reduce to a jam thickness, strain and add seasoning if needed.
  3. For the burnt lime gel, cut the limes in segments then grill them until blackened, remove the flesh and zest then add to a pan with the sugar with some lemon juice also, boil and reduce down, once ready strain and add to another pan, now add the agar agar and whisk in, pour onto a tray and cool it down, once cooled blend thoroughly until smooth, lay it back on a tray and vac pack to remove all air bubbles.
  4. For the fennel, vac-pack with lime juice, garlic, salt and a bit of oil. Sous vide this for about 30 minutes at 85 degrees celcius or until tender. Once tender remove from vac pack and dry on a tray with a j-cloth, when serving sear off in a pan, season and finish with the burnt lime gel drizzled on top.
  5. For smoking the duck, remove duck breast from the half duck, dry out and hang in smoker for about an hour on a cold smoke, once done remove from the smoker, season and sear off for service cooking to medium rare, paste with garlic and rosemary.
  6. For the lime and rosemary crumb, toast off some rosemary in the oven, remove and blend together with the lime zest and salt.
  7. For the duck kushi, remove the skin from the duck leg, de bone and open the leg. Dice the leg into 3x3cm squares then layer on top of each other onto a skewer, glaze with cumquat then score the duck skin, wrap around the skewer and secure the skin. Sear the skewer off on a low-medium heat to get a golden colour, place into the oven to cook through, once cooked remove from the oven and roll in the rosemary and lime crumb.
  8. For the cumquat glaze, squeeze the juice of a singular cumquat and reduce right down to a syrup.
