Here is a casing finder I found helpful. https://www.makincasing.com/casing_finder.aspWhat size sheep casings do you guys use? I googled it and said 22-26mm but I also saw somewhere else that it was 18mm. Seems to me like it would be closer to 22, but want to make sure before buying some. Just had this sausage for the first time and it's great. Going to be making this recipe soon!
