Ingredients

  • 1.5 kg Lamb shoulder
  • Sea salt and freshly ground black pepper
  • 3 Cloves garlic Peeled and chopped/crushed
  • 2 Large onions Peeled and cut into chunks
  • 3 Large carrots Peeled and chopped into chunks
  • 400 ml Lamb stock
  • 3 tbsp Cornflour
  • 100 g Mint jelly
  • 2 tbsp Soy sauce I use reduced salt

Instructions

  • Put the garlic, onions, carrots, lamb joint and stock into the slow cooker. Add salt and pepper.
  • Cook on HIGH for 10 hours or LOW for 12 hours.
  • When cooked, remove the meat to a tin, smother in the mint jelly and bake in the oven at 220C for about 20 - 30 minutes or until browned.
  • Remove the carrots and onions and set aside.

To make the gravy:

  • Using a spoon or a gravy seperator jug, pour off the fatty layer from the cooking liquid in the slow cooker. Discard the fatty part.
  • From the remaining cooking juices, remove a small amount of the liquid from the pan (say a tablespoon or two) into a mug or bowl and stir in the cornflour into it until it dissolves. Add a small amount at first and stir in, keep adding until you get a thick paste.
  • Add this 'slurry' back into the pan, pour in the soy sauce and stir. You can leave this in your slow cooker on HIGH for about 30 minutes, or if your pan is able to go on the hob, pop onto the hob to bubble for 10 minutes until thick.

Notes

Searing the lamb: You get a much better result with this dish by browning AFTER cooking rather than before. The result is crunchy on top and soft underneath.
Cut of lamb: You can use a lamb leg instead of shoulder (if you can fit it into your slow cooker). It may take a little less cooking time depending on the size.
Timing the cook: You can either put the lamb on overnight and cook it on low for a little longer (it’s very difficult to overcook lamb shoulder) OR use a timer plug like this one to start the slow cooker overnight. 
Finishing this off in the oven: You don’t have to do this step if you don’t want to, but it gives a delicious crispy golden glaze if you do. You can serve the lamb straight from the slow cooker and it will still be meltingly tender, it just won’t have any colour.
Excess gravy fat: Spoon the layer of fat off the top of the cooking liquid before making your gravy, or use an Oxo Good Grips Gravy Separator for this job.
