I want to get a slow cooker to feed 2 adults and two children. I'm unsure what size to get, will 3.5 litre be too small?. Ideally, I would like to be able to cook a meal and have enough left over to freeze for another meal. Would I be able to do this with a 4.5 to 5 litre one?
Is it very useful to have a crock that you can use on the hob and in the oven?
Any other features I should look for or avoid?
Any particular good brands/models?
Thanks in advance.
