It doesn't need to be binary. You can always mix cooked sauce with fermented to get the flavor profile you are looking for.
Totally different artist, but thanks for reminding me that I haven't listened to Tony Levin in a really long time :-)
Technical stuff is important, but for menu development, I'd partner with an experienced creative musician who can confidently manipulate abstract concepts over someone who'd memorized a food science text book, any day.
At a certain point don’t the cultures you’re fostering run out of food?
I make a lot of hot sauce (grow my own peppers) and usually just make a mash, boil that for a bit, and then essentially can it. If the pH is low enough and you pasteurize everything & sanitize your equipment, it's shelf stable for a long time.
I also started growing peppers, and this was the only way we could keep the many gallons of hot sauce a tiny bed of peppers can produce.
It does change the taste, which for some, might be a downside.
I'd love to have one of these. What's the store?
