@parksider Like @Parksider is saying, make sure you keep it under boiling. 170 SEEMS to be the best temperature at this point. Also, Collagen Casings might struggle with being put directly into the water as they aren’t designed for that, you could either use a different casing or you can vac pack them before putting them in the water. I guess you could actually also put them in just a zip lock back with all the air forced out as well?
