Sherm, I've looked into the stove top kind and the heat adjustment is your burner. I have not got a clue on how to heat a stove top pressure cooker properly. Wouldn't even know where to begin.
I have a super energy saver stove. It takes 8 minutes to bring 5 cups of water to a biol.
On all other stoves I ever used, it only took about half that time. 3-4 minutes to biol water.
(I don't see where I'm saving any energy running the burner longer.)
No, a manual pressure cooker is out of the question. I can see me blowing one up in my kitchen especially if nature calls toward the end of cooking.
(At my age, I never know when I'll have to go. I have learned to never trust a fart, though.)
Anyone who's never tried using a pressure cooker before, or even thinks that they're dangerous without even trying to learn more about them, they'll quickly assume the wrong things about them. And one automatically assumes that the worst is about to happen. Their #1 fear above all else, believe it or not, is that it might blow up during use.
But when used properly, and according to the manufacturer's instructions, they are just as safe as an ordinary pot. I still have YET to hear about one having blown up. Because there are built-in safety features that help preclude that mishap from ever happening.
They're met with very strict manufacturing safety standards and comply with Underwriters' Labratories (their 2-letter logo is stamped on these and most other comsumer products for home use), meaning that they are very safe to use and meet or exceed all safety requirements set forth by the U.S. Gov't. The only time that they would ever become dangerous to use is if the owner or consumer messes up in some way and puts himself or herself in harm's way. This is why very strict instructions are given and should be followed with each one.
Respect the unit and the use of one, and it'll give you many, many, many years of safe, trouble-free reliable and enjoyable operation. Replace the gaskets, handles and other parts when they begin to crack or wear out (I've done that with one of mine, I've replaced the gasket and handles, and it still works like new), and you'll be helping the unit maintain its reliable trouble-free & safe qualities.
In other words, treat it right, and it'll be your friend for life. Just make sure that you "dot the i's and cross the t's". That's a true guarrantee!
And if nature calls during the time that the unit is in use, then just turn the burner down a little until you came back to the stove. I can't even BEGIN to tell you how many times nature has called while I was cooking something in any of my 3 pressure cookers!!! You['l be fine. But if you still feel that the cute li'l Deni unit might work for you, then by all means, go for it!!
You CAN improvise however, by browing the meat in a skillet before putting it in the pressure cooker. I'll help you if you decide to get the Deni unit. I'll be new at using an electric one. My manual ones are safe to use, and I keep them that way.
