Question....

I can regulate about 200-220deg. in my cooker. Is that too high?

That is a perfect temp. When I make it in the oven, I keep it right between 200 and 240ish


Second.....How do you store it after its ready?

After it's done cooking? I set it out for a while (on the counter or any available space) and let it cool down. After that, just put it in a ziploc bag. Simple as that.


Third.....How long would I cook it at 200-220deg?

It depends on personal preferance of course, but it's gonna take atleast a few hours. Depending on how thick the slices are, mine usually takes anywhere from 4 to 8 hours.
