The more I read this, the more I'm convinced the author has zero actual experience with food.
Nah, there are actually some interesting comparisons.
For chapter 2, you can compare the bonefish to eggs; too low of a cooking temperature is bad because pathogens can survive, and too high will create the green sulfurous ring around the yolk. Obviously, there's a much larger edible range for eggs, but there's that "ideal" temperature for getting a jammy, soft-boiled egg.
Chapter 3 is mostly just storytelling, but stone fruit pit liquor is an actual thing.
Chapter 4 is raisin wine. Most fruits can only be sundried because they have enough sugar or acidity to prevent spoilage; the water grapes, which are not only very dilute but "fist-sized" (making them slower to completely dry), would not sundry well.
... Actually, it might be closer to icewine since you aren't getting the caramelization from sundrying. Hmm.
