Pressure cookers
We currently use three different pressure cookers. We have:
- Mirro M-0522-11
- All American 930
- All American Electric Sterilizer 75X
The first two we inherited and the third one we purchased for the lab this year.
If you need parts for pressure cookers, here’s an American site with a great selection. Order extras so you don’t have to pay shipping twice!
