  1. Marinade the lamb

    In a large, non-metallic bowl, whisk together a marinade for the lamb with 3 crushed garlic cloves, 2 bay leaves, 1 tbsp Dijon mustard and 400ml red wine. Make multiple 1cm deep incisions in the lamb then submerge in the marinade. Cover and chill in the fridge for a minimum of 2 hours or overnight. Remove the lamb from the fridge 1 hour before you’re ready to roast.

    Can't find Dijon mustard? Try using 1tsp English mustard instead, or a teaspoon of mustard powder. Red wine can easily be replaced with white.

  2. Prep the veg

    Preheat the oven to gas 6, 200°C, fan 180°C. Roughly chop 2 carrots, 3 celery stalks and 1 red onion. Tip into a large roasting tray and spread out in an even layer. Add 3 sprigs of rosemary. Remove the lamb from the marinade (reserving the marinade for later) and place on top of the vegetables. Season and rub with 2 tbsp oil.

    The veg used here is just to add flavour to the gravy, so if you can't find carrots, celery and onion they are not essential - use a little bit of whatever veg you have at home.

  3. Roast and rest

    Roast for 30 mins then pour the marinade into the roasting tray. Reduce the oven temperature to gas 4, 180°C, fan 160°C and roast for a further 2 hours 30 mins. Remove the lamb to a plate, tightly cover with foil and leave to rest for 15 mins.

  4. Strain the juices

    Meanwhile, make the gravy. Strain the juices from the roasting tray into a saucepan and add 150ml chicken stock, discarding the veg.

  5. Make the gravy

    Remove 3 tbsp of the liquid to a small bowl and mix with 3 tbsp plain flour to make a paste. Add this back to the saucepan and simmer for 10 mins. Stir in 2 tbsp redcurrant jelly and any resting juices from the lamb.

    Redcurrant jelly will add a nice sweetness to your gravy, but if you don't have any you can use a couple of teaspoons of whatever jam you have at home.
