I mentioned to MIL that I was thinking about getting a slow cooker. I was planning on doing a bit of research first but she went out and got us one anyway. Not that I'm not grateful but it is huge, has 6 litre capacity & the recipe book that comes with it has recipes for between 10 and 16 people. We are 2 adults, 3 DC's (all under 3). So, I am wondering if it will be efficient for cooking much smaller amounts or if I should try & see if I can change it for a smaller model. Any advice?
