I've been given a slow cooker. I have bought some meat thinking I would make a stew this evening for tomorrow's dinner. The timing doesn't seem to work. The recipe i have takes 7 hours - if I start it now ish I'd have to turn it off at 1am when I'm asleep. If I start it in the morning I'd have to turn it off at 2pm when I'm at work. I'm clearly not getting this. How do I fit it into my day??
