Presto01781 Pressure Canner and Cooker, 23 qt, Silver

I use a canner for mushroom cultivation. The last canner I had was smaller with no gauge to tell you when you had reached 15 p.s.i. Consequently, there were few times when my rye berries did not reach full sterilization, which ultimately resulted in mold. No such problems here. I confidently have quality mushroom cultivation every time. I'm very satisfied with my purchase

I love my presto I have three , I find the ease of use much better than my American cooker , If you clean and keep your gasket lubricated these pressure cookers will last you for decades , let’s just say I use these every week in mycology and for the money these are a top pick and have served me well over the years . When it needs maintenance the parts are simple to replace and order . Live my prestos !!

I just received my unit and although I have not used the unit, I have read the book completely and called presto and they say there's no need to have the gauge checked. If it's new, it's ready go to, just follow the cleaning instructions on page 6 and 7 of the book. They also state there's no reason to buy another 15lb rocker because it comes with one. I ordered the extra rocker for $12 but the unit came last night and has a 15lb rocker in it. Pressure regulator would be the better more proper term, not rocker. I also work in the air pressure industry for a living and we rarely test our gauges unless something obvious is happening and we have variable testing at our facility that goes from 10psi to 300 psi, which that kind of pressure can be dangerous. So I'm not sure why people think they need to get their gauge tested. Even if the gauge is faulty, the rocker is going to rock at 15lbs and never let the pot get higher than this. Additionally, the books states there is a vent pipe (page4) is the "primary pressure relief valve and will release pressure in excess of 15 pounds. The pressure regulator sits loosely on the vent pipe." That's a quote. So this unit is designed to be at 15 lbs or below which the pot can handle. I'm not sure why anyone would blow the lid off unless they rolled their rubber ring, their ring was old or not seated properly or the top was not locked. Again, I haven't used the unit yet, and will follow up soon with a review on that, but from my perspective, I'm going to can tomatoes over the next couple of days and that is 11 lbs of pressure which means I will need my gauge and my rocker should never rock. I have to play with the heat to find where my stove dial holds the pot at 11 lbs and make sure I never see the pressure regulator move or that means the pot has reached 15 lbs. ?? Some of these reviews were confusing and also caused me to buy a 15 lb regulator that came with the unit. It seems unnecessary. ?? Sure seems it's ready to go out of the box, no need to check or buy another item.Okay, I went home and used it last night. I have updates. First, this is a great unit. I can't imagine anyone blowing the lid off if you align it and lock it down. I filled it with water, put it on and ran it up to 15 lbs of pressure. On my stove it took 19 minutes to get there but that's going to vary. I think I understand why people suggest getting the variable weight. In my case, I can a lot of tomatoes. I need this at 10-11 pounds for 15 minutes. I either have to play with the heat setting on my stove to get it to stay at 10-11 pounds, while keeping an eye on it, OR if you buy the rocker weight that is 5-10-15 lbs, you can take it apart, make it a 10 lb rocker and just set it and forget it. I see the logic but don't think that makes buyin the other part necessary, it just saves a little time. Plus, for tomatoes, they suggest 11 lbs. If you are anal and want 11, the variable weight can't do that. if you don't mind 10-11 pounds, no big deal. Either way, I didn't take my cooker to have the gauge tested, This is ready to go out of the box. Just make sure and put a little oil on the ring to keep it in good shape and you might just want to have a back up ring on hand as the unit ages so that on that weekend you want to can, if the ring splits, you slide the new one in and keep going. Great unit and it's HUGE! I love it.Another update...this baby is getting a good workout. Canned a bunch of sauce last night, working on more as I type. We bought the additional weight/rocker that you can make 5-10-15 pounds. Put it at 10 pounds and let it pressure for 16 minutes. Gets the tomato sauce in the jars up to 240 degrees killing all that might be present. Great pressure canner. Highly recommend. Again, still don't understand how anyone could blow the lid off if you align this properly. No blown lids here. Just gotta read the book and use it properly I think.Another update - well, we've done 7 gallons of roma tomato sauce, 5 quarts a session and this pressure canner is great. It's so easy to lock the lid. I've also realized it has a special lock that when pressure starts to build, but even before it can be read on the gauge, the lock pops up and there's no way you can open this canner with pressure so no danger. I will say that when my 16 minutes at 11 lbs for tomato sauce are up, I take a kitchen knife and lean the pressure rocker over to let the steam out quickly. Within 4-5 minutes, all the pressure has bleed out, the lock goes back down and I take the lid off. This is not in the book, but I was just dying to see how the jars looks. As I took them out, they were still boiling and we put a laser temp gauge on them and they were reading 210-215. Given the heat was turned off over 4-5 minutes ago, it's reasonable to assume it was indeed up to 240 which is what is needed to kill all the stuff for tomato sauce. Keep in mind, this is different for every food, for every size and for every elevation. So read the book for your food and it will tell you what to do. I recommend citric acid as well as the adjustable pressure regulator (rocker) and a canning kit, particularly to get the jars out. Taking them out at 215 degrees is careful business. But it's cool to see them boiling inside the jars. And within 10 minutes, they are down to 160 which is when the 'tinning' or vacuming starts. As you know, the cooling is what causes the air tight seal, not the pressure canning. Pressure canning is to raise the temp up high enough to kill all the germs, when you take them out, they do the tinning sounds and you can hear all the tops going ting, ting.....ting...then you know you are getting a great seal!

I am extremely satisfied with this product! It works exactly as advertised and meets all my expectations. The quality is outstanding, and it's incredibly easy to use. It’s well-built, reliable, and has made a noticeable difference in my daily tasks. Whether it's performance, durability, or ease of use, this product delivers on all fronts. I would definitely recommend it to anyone looking for a top-notch solution. Five stars!

I love my Presto Pressure Canner. I works great! I've been canning non-stop. Very durable pot and easy to use.

Good quality. Affordable

Bought the wrong version by accident! Of course it's too late to return it, lol. But, I do have a ton of canning to do, so I am not unhappy. I'll use it on the grill outdoors that I intend to build. And I will buy the correct version for my induction cookplate.

Great to seal your items and squirrelly them away when you want to. I plan to use them for canning from our garden. So happy with the plans and use. The size is perfect for what we need. The heat level works well for canning cucumber and pickles and other items. The quality will work for what we need. Pleased with this purchase and will recommend to others!!
