If making a chicken (drumstick) curry in a slow cooker, how long would I need to cook it for? Could you please give me times on high and low. I'm hoping to make Mamta's butter chicken curry. thank you!

You will have to look up cooking times of your individual slow cooker, but I usually leave it on 'high' for a couple of hours and then another 3-4 hours on medium. I am usually around the house, so don't very often use slow option, but you will probably need 7-8 hours on that.
