I think the "soul" is coming from the fact that a human has worked, experimented, and tested with their physical senses a specific recipe until it tastes good. There is physical feedback involved. This is something an LLM cannot do. The LLM "recipe" is a statistical amalgamation of every ramen recipe in the training set.

Or they just wrote down what their grandma used to do and changed how much salt they put in the water.

Or they read a few recipes and made their own statistical amalgamation and said "hey this seems to work" on the first try.

Or they're just making stuff up or scraping it and putting it on a website for ad money.

"Soul" not required.

Also does an LLM give the same recipe every time you ask? I'd wager you could change the context and get something a little more specialized.
