I just discovered the usefulness of the thermal cooker (I have a Tiger brand, induction friendly, which I bought off Amazon Warehouse for a significant discount). I transported sauerbraten to another home and it kept the meat and sauce at a perfect temp for quite some time. I did a pasta meat sauce and it held it at piping hot for 6 hours until service.
I just have to get used to thinking about using it for what I plan to cook. I've never been a fan of slow cookers due to the vagaries of the temperature control of them.
