We still don’t know if the pineapple was fresh or canned. So there is that, but if it was fresh, the average pineapple (fresh) weight is 2 pounds. That is 8% to meat weight of fruit With 25# meat. This is an unworkable percentage of fruit generally.
This amount of pineapple may work in a fresh sausage made and cooked today, but won’t work in a cured sausage smoked tomorrow.
