1. Combine all ingredients except the meat and cornflour in the slow cooker bowl. Mix well.
2. Add the meat cuts and coat generously with sauce. (You can brown the meat beforehand but I don’t).
3. Cook for 8 hours on LOW.
4. Remove bay leaves and bones as the meat will have fallen off them. Carefully break meat chunks into smaller pieces then stir.
5. Make a slurry by mixing the cornflour with a small amount of water until it reaches a pourable consistency. Stir into the dish and cook for a further 10 minutes to thicken the sauce. Repeat if necessary.
