Just finished my first batch of summer sausage. Need to thank everyone who contributed to this message string. I only have a Traeger smoker and I was worried about it running too hot for summer sausage. The temperature swings on that thing are mind boggling. So I opted for sous vide instead. They turned out great! I followed the Waltons recipe for summer sausage (I went with habanero bbq seasoning based on the recent podcast) but I did cut the water by about a third since these were going into the sous vide and not a smoker. Total guess on 2/3 water being the right amount to account for no water loss in the sous vide. I did a 10 lb batch which called for 3.5 cups of water and I used 2 cups. It looked right in the mixer and I had 1.5 cups left in the measuring cup.
After Jon’s recommendation that they stay above 130 for at least 3 hrs I followed the temp schedule below. Don’t know if it was excessive stepping up this way but hey it worked.
110 F for 30 min
120 F for 30 min
130 F for 1 hr
140 F for 1.5 hr
155 F for 1.5 hr
