I have been in search for a summer sausage seasoning with black pepper but couldn’t find one. I’m new at this so the H Summer Sausage is the only one I have used so I can’t give you any comparisons with the other 3, but you mentioned black pepper so thought I would share my first experience.
So I used Waltons H Summer Sausage and mixed in about a quarter cup of fine black pepper. I liked the results and several others did as well. It had a light pepper taste and I probably will add a little more in the next batch for a slightly stronger flavor. I used 25 lbs of venison and 4lbs of beef fat to keep it on the leaner side. Good luck, Bob
