I have read that you can make apple butter in a slow cooker. They used
to be called crock pots, but modern crock pots boil food, even on low,
so that you do not get poisoned eating improperly cooked beans, or ill
from undercooked meat.

Being outside the US, I was able to buy a Kenwood slow cooker, which on
low peaks at 180F. It takes 3-4 hours to reach that temperature, and
if full, stays there.

I have used it successfully to make dulche-de-leche, and want to use it to
make apple butter.

What I have read says to put apple sauce in the pot and cook it for 3 days.

I was wondering, because my pot is so big (about a gallon), can I place
cans of apple sauce in it, fill it with water and let it sit for 3 days?

Will this do the job?

If I am careful to dry the cans, so they don't rust, can I leave the Apple
sauce (hopefully now apple butter) in them? At room temperature?

Thanks in advance,

Geoff.
