Dear Rabbi Simon
I think I asked you about my slow cooker a while ago.
I am hoping to use the slow cooker over the chag – it says “don’t use a timer” (but doesn’t say why – so I hope to try using a timer before Pesach to see what happens! If it doesn’t explode, it should be safe!).
My question is: The pot in the slow cooker is ceramic. If I’m correct, ceramics can’t be kashered for Pesach. I always use a “slow cooker liner”, so the food doesn’t touch the pot directly. Can I thus use it for Pesach?
Interesting question re slow cooker liner. If you are confident that you have only used the ceramic pot with the agency of a liner, you may use it in this way on Pesach as well.
To be on the safe side I would advise using a double liner during Pesach. You do not need two new liners every time. You can re-use the same additional liner repeatedly (as long as it is clean).
