Tips
Pour water from tray before shredding meat in the pan, or place lamb on a chopping board for a more stable surface.
After shredding, check the seasoning of the meat and add a squeeze of lemon, salt or pepper if desired.
Lamb can be cooked and shredded in advance. Reheat to serve.
2 hours is the minimum cooking time to be able to shred the lamb. If you have the time, leave the lamb in the oven for another 30 minutes to 1 hour. It will only get better and easier to shred.
Try different ingredients in the slaw such as beetroot and apple.
