Place the hocks, split peas, leek, onion, garlic, turmeric, carrot, celery, chilli powder, stock and 2 litres of water into the slow cooker bowl. Cover with lid. Use the MENU button to select LOW SLOW COOK. Adjust the timer to 8 hours and press POWER/START to start cooking. If you want to put on before work, place on low and cook for 9 hours. (or select HIGH SLOW COOK for 4 hours)

Remove hocks from soup carefully using tongs and place them in a large bowl. When they are cool enough to handle, pull the meat the bone in bite-sized shards, discarding excess fat, gristle and bones. Shred meat into large pieces and transfer back into the slow cooker. Add lemon juice and stir to combine
