       | 
       | Sous vide was my first thought, since that avoids the evaporation
       | and oxidation that decreases the intensity of the low and slow
       | method. However I don't think botulism is any more of a concern
       | here than any other sous vide dish and high heat doesn't kill
       | botulism spores so it doesn't really matter how you cook the
       | chilis.
       | 
       | Just keep it above 140F while infusing and keep it out of the
       | <130F danger zone past a few hours. Quickly cool it below 45F
       | using an ice bath after infusing if you're paranoid or cooking
       | for someone that might be immunocompromised.

         | I did sous vide chilli oil by placing the oil and chillies in
         | glass canning jars in the water bath. I let them rip for about
         | 90 minutes at ~88degC/190degF and the results were pretty good.
         | I like the roasty/mildly bitter results from flash heating, but
         | this was quite smooth and pleasant.
         | 
         | I think some purists would think it tastes weird. It's a very
         | "clean" chilli flavour. I think it would have been a lot better
         | with more aromatics, and when I'm done with this oil I'll
         | likely give that a shot.

         | Yeah I might give it a shot (although I gave away my sous vide
         | machine). But low and slow isn't always better for extraction.
         | Coffee for instance extracts more with a fast infusion versus
         | cold brew.

           | Coffee extraction usually happens in a closed vessel where
           | the volatiles aren't as exposed to air and can't as easily
           | evaporate. The advantage of sous vide isn't just the cooking
           | temperature but the fact that the ingredients are completely
           | sealed. It has a significant impact on many ingredients like
           | chicken or carrots, which can stew in their own juices
           | instead of reducing.

             | That's not necessarily true. A clever dripper does open air

             | perhaps with oil more volatile aroma compounds are
             | released? Either way the only solution is to try it!

       | I use Korean red pepper flake, the same type I use in my kimchi,

       | them out before leaving black cardamom Sichuan green chilis (for
       | a more woody note) star anise cinnamon and coriander seed for a
       | brighter aroma. I also mix black vinegar and salt in with the
       | chilis first before decanting the seasoned oil atop them. I make
       | a litre at a time but can't ever keep it in the house. The whole
       | effort is 1-2 hours but its mostly just watching the garlic and
       | onion and making sure to pull it out before it burns. The
       | decanting doesn't generate smoke or anything troublesome but
       | beware, the smell of chili oil will permeate the kitchen for
       | about three days.

             | My point is that it is silly to complain about people being
             | nerdy about a specific topic, just because there are others
             | with more expertise. Especially in cooking, the concept of
             | "inventors" and "authorities" for such basic things as
             | chilli oil, is a strange one.
             | 
             | For me personally, getting deep into a specific food item
             | like this is bascally like traveling. I will first do my
             | own experimentation, not because I think I will discover
             | something new, but because I will more deeply understand
             | why things are done the way they are when I (later) read
             | "proper" sources and consult with others. At that initial
             | stage, I am bound to overcomplicate things, but it's the
             | good kind of overcomplication.
             | 
             | It is like traveling to a new place, and walking around
             | randomly before opening a map. Of course I
             | "overcomplicated" my path from A to B, but I've seen so
             | many interesting (but not necessarily important) things on
             | my way.

           | 
           | For example, I absolutely love aquascaping. I have a very
           | scientific understanding and appreciation of it all, but it
           | doesn't diminish how incredible and beautiful it all is for
           | me. Some people look at it from a very aesthetic point of
           | view, and to me it's often like some glorious chemistry and
           | biology event occurring in front of me. I marvel at the fact
           | that the nitrogen cycle is happening in this little slice of
           | biotope. I love to test the water parameters and log what's
           | been going in and out to better understand how it's working.
           | I make nerdy little movies of the plants and animals. But

           | significantly more, or finds it more beautiful in more
           | meaningful ways. I just process it differently.
           | 
           | With the chili oil, understanding and experimenting with it
           | can be part of how a more cerebral person engages with their
           | appreciation, curiosity, or passion about the oil. Nerding
           | out might just mean the person really loves it, and that's
           | how they go about it. It's all good. Maybe they'll figure out
           | a bad ass recipe that'll make the rounds eventually, and
           | everyone can enjoy it.

       | 
       | For example, I had a roommate who would cook salmon in a tomato

           | adults to die of food poisoning from cooked food going bad*.
           | It's mostly children, the elderly, and the immunocompromised

       | One thing the author misses about the oil choice: what makes
       | caiziyou superior to other oil choices is that it has a high
       | viscosity. That results in the chili oil sticking to food and the
       | tongue better once used; it probably also affects the fluid

       | I have found that smoked chilis lose their smokiness with high
