    Explains pretty good how pressure cooker can cook tough meat in 45 minutes vs boiling in a regular pot in 3 hours.

    • Mostly Everything
      Mostly Everything 3 months ago

      But bruh, if you pressure cook, it can tenderizd the meat in 6 to 8 mins and if you open cook it at low heat for 45 mins, it will be soft and tender, what kind of pressure cooker are u using though coz that's all loooottt of time

    • Jon Smith
      Jon Smith 3 months ago

      @Zack Stump my guess is that it would work basically the same as the slow cooker and still not work.
      You’d start off with basically zero pressure in the cooker. Heating would increase the pressure a tiny amount I think from anything released from the food but I doubt enough to add enough pressure to significantly change the boiling point.

      @Renee Brutvan indeed.. out in the rockies some pasta boxes will have different boiling instructions based on your altitude.. i think the bp of water in denver is about 94-95C so it needs to cook alittle longer

    That is why Pressure cooker is better at cooking things.
    It elevates boiling point of water far above 100°C.
    Pressure cooker is a must at higher elevations.

    • Ld Alexandrite
      Ld Alexandrite 4 months ago +2

      @Emerson Mora oh if you’re talking about boiling point _increasing_ it happens at places with higher atmospheric pressure, aka lower altitudes. But the boiling point is _decreased_ at higher altitutes, like it’s 90-something degree at 2000 meters if I’m not mistaken.
      That’s why they said pressure cooker is a must. It increases the boiling point, I think it cooks more throughly that way

    • Ld Alexandrite

      @monsterhunter445 the boiling point just increases relatively. 100 degree celsius at sea level, but it goes 110, 120 etc. further below.

      My hometown sits in 2100 meters altitude. We use pressure cooker for cooking meat, almost all the time. I’ve never thought _this_ was the reason!

  • Weston Ding

    How about cooking in an “oxygen less” environment? I know the oxygen does not heat the food (except when some things burn) but can you use the pressure from a different gas? How about cooking in pure oxygen (at half atm or less to be safe)? [Note: the heating source can be out of the chamber.]

    • n k
      n k 4 months ago

      @Weston Ding you're overthinking things, all of your experiments can be done with a smoker (changes the gas composition to something preferable than oxygen), a sous vide machine, deep fryer, or through braising.
      Those test cooking in an environment with a high ratio of other gasses, no gasses and no outside liquids, cooking via oil, and cooking via other liquid (usually broths)

    • Max Pulido
      Max Pulido 4 months ago +1

      @Weston Ding Most cooking isn't done in pressure cookers. And even there, most of the gas is not oxygen, especially after you begin.
      And yeah, I'm sure most of it's not dependant on oxygen except for the fuel.
      It might change the taste of aerated wine or something in a predictable way. I don't know about anything boiled though.

    • Weston Ding
      Weston Ding 4 months ago

      @Max Pulido Yes. Apollo 13’s harrowing situation involved such a problem with its oxygen tank. How about at a much lower pressure of pure O2 (like 1/4 atm)? I can imagine that if it reacts, it will be a limiting reactant.

    • Weston Ding
      Weston Ding 4 months ago

      @Max Pulido yeah. But do the gasses dissolve or react a little bit or affect the flavor? Without O2 some reactions don’t occur. Pressure cookers generally use some atmospheric compositions combined with more water vapor.

    • Max Pulido
      Max Pulido 4 months ago +2

      Cooking in pure oxygen is just dangerous, but yeah, you can cook by just exposing your food to hot gas. That's how ovens work. Actually it's how cooking in fire works as well lmao.

      It's the same outside the vacuum changer, just different. That's why however much you heat a pan of water it will never go above 100C while it's boiling - the boiling cools it as fast as the stove can heat it.

    When I was 6 I observed my mom boiling...something (I don't remember what) Anyway I thought that the stove was just blowing bubbles in to the water water and that's what cooked food. My dumbass then concluded that if I blew bubbles in something long enough it would cook. I got some pasta and put it in a cup of water and blew bubbles in it for 30 min....well in hindsight it probably was only like 15 min. It just seemed like 30 min. Regardless the pasta softened up ever so slightly so I thought I proved my hypothesis. After that day if I blew bubbles in any drink I would then refuse to drink it anymore claiming that the drink was then partially cooked and tasted different. My mom was confused but would always pretend to get me a new drink and just pour the old one in a new glass. Hahah. Damn I was a dumb kid. It's a wonder I didn't stick a fork in a light socket or something equally stupid. Lol

  • David Clawson
    David Clawson 3 months ago

    I think the burned parts are interesting, considering the rest of the contents are “cold”. My guess is that it’s similar to something that they deal with in boiler design: avoiding the Leidenfrost effect.
    Steam, while usually really hot, actually is a very poor conductor of heat when compared to liquid water. Boiler designers and operators use special charts to make sure that their boilers operate in a way that steam doesn’t form in parts of the system where the fire is, because the metal walls would heat up faster than the steam-insulated water could carry away and it could cause the metal to lose strength and explode, which would be very bad, obviously.
    Maybe another step in the experiment: get a plate of infrared transparent glass and put a window into the chamber and an IR camera from a place like FLIR on the setup. You could have it show the temperatures involved along the way. Maybe do a side by side in atmospheric, too.
    Very cool!

    You'd have to increase the pressure to cook it instead of decreasing the pressure.... Pressure in cooking is needed because the thermal conductivity lowers in a low pressure system.

  • Andrew Rasmussen

    Commercial jams are sometimes cooked at low pressure - this makes sense because you need to boil off some of the water in the fruit before it will set properly and the low pressure saves on heating energy.
