Does the meat have less firmness than any other type of “normal” sausage? I wonder if you are comparing stiffness and texture to a dry cured pepperoni…? What some people think of as pepperoni is not processed in the same way as other sausages like brats, summer sausage, snack sticks, etc. It can be a true dried sausage that is fermented and dry cured, but not ever truly cooked or thermally processed. That is a lot of what gives pepperoni it’s hard firmness and specific texture when eating. That is just not something that can be completely replicated in a cooked sausage. I think the dryness is a big key there, but the texture cannot be fully emulated if we are comparing something thermally processed to not.
Other than that, what I think is one of the best ways to make pepperoni, without doing the old-world dry cured and fermented sausage, is what we go through in our standard pepperoni recipe shown here: https://meatgistics.waltonsinc.com/topic/545/how-to-make-homemade-pepperoni-recipe
I would check out your process compared to that one, and see if there are things you can change to match it.
The last time we made pepperoni here, it was amazing!!
