NYKIDIES, cure under a vacuum question

[Nick]

And thank you for the book recommendations, I will ordering a few books today.

Here is the recipe I am questioning. There are no cultures , so why the 80 deg for 12 hrs? And why with a similiar recipe does umai’s recipe for lonzino require no 80 deg hanging before it begins to dry?
