I’m sure it has to do with the extra labor involved with fresh. Also, the added steps required when working with raw pork around pizza toppings. Being in BBQ, you have a pretty good setup for that I assume. I would like to grind and mix my own, but there’s the space required and the room to keep from cross contaminating things in the grinding/mixing area. So I have found a great frozen ground bulk Italian sausage in 5lb bags. I thaw it, then pinch it onto full sheet pans. Then I put it in the oven for 5 minutes. Count me among the nervous about using raw topping directly on the pizza. Plus, I don’t want the raw pork on the make line. Cooking it also gives me more time before it goes bad, which is pretty quick once ground meat hits air. Anyway, after it comes out from 5 mins, I drain it as much as possible and chill it in a Cambro. Then it goes on the make line. After the 10 mins we bake our pizza, it comes out great. The extra steps are worth it for the improved product. And, as with all the things I’m making myself such as chicken, it comes out cheaper than the pre-made stuff.
