Review: Stands up to Pressure Cooker 15psi - It's just what you want it for. They work. I think out of 500 bags, maybe, one has busted and that's because I tried using it a second time after contamination. It's a good product. If they keep the same manufacturing process and use the same material, I can recommend. This is July2024.

### ⭐⭐⭐⭐⭐ Work Great if Used Correctly
*by D***K on January 16, 2022*

These mushroom bags work great but they will burst in the PC if proper precautions are not taken. First, they cannot come into contact with the bottom or sides of your pressure cooker (PC). The PC will get very hot and it will melt the plastic. I place metal canning rings under the canning rack and then drape cloth over the rim of the PC arranged so that the interior is completely lined with cloth. Then I load the bags and then fold the cloth over top of the bags to clear the rim of the PC once loaded. Second, you cannot have any air in your bags or they will pop. The air expands under pressure — a lot! — and the filter patch does not provide enough ventilation to allow excess air to escape. The bags will then pop, and you will probably hear it. There are a couple of ways to prevent this. One is to not seal the bags until after they are PCed. This does complicate sealing the bags because the PC will wrinkle and distort the plastic. It is also not foolproof because if the bags are rolled tightly closed as per common practice then they could burst anyway. The safest way to prevent air from bursting your bags is to just not have any. Push all the excess air out of the bag so they look like they are vacuum sealed (which btw is impossible with these bags because of the filter patch). . Once all the air is out of the bag you can seal them and PC or else PC first as per your preference. I personally like to seal the bags before pressure cooking because they seal better, and I can verify that the excess air is fully removed before they go into the PC. If the air is not removed then you will observe a noticeable pillow of air inside when you try to roll them up. I seal my bags as close to the top as possible so that if necessary I can open the seal, remove the excess air, and still have enough head room to reseal the bag. If you follow these precautions then you can avoid bursting your bags on the regular.
