You might want to cook this for as low and long as possible to get your meat as tender as you can, which might involve cooking it overnight if you want it ready for lunchtime. It will take 7 hours on the lowest setting, so the best thing to do is to invest in this inexpensive smart plug (it’s my favourite) that allows you to set a timer to switch your slow cooker on at a particular time during the night. Don’t forget to press the ‘on’ switch!
