We have made venison breakfast sausage and we got the spice mix from Penzeys spices. We did several actually. We made one up with their Bratwurst seasoning and like that alot. We have grilled "bratuwurst burgers" and load them with onions, peppers, etc. So much easier than trying to find casings. Penzeys have stores, but also sell spice mix online. We also made a batch from a recipe that we googled...and then tweaked it a little to our taste....so I really like the idea of frying up a little sample when you are making it to adjust the flavor if needed. We didnt do huge bathces, so the purchased seasoning mix was not too expensive, but if you do alot, it might be better to make your own seasoning mix. Best of luck to you! Oh, and one of my favorite ways to use our venison breakfast sausage is in "scrambles" and also in many overnight dishes with bread /cheese, etc. that you let set over night and cook in the morning.
