We've got some frozen pork sausage meat that we will be thawing and stuffing into sausage casings. We think we would like to cold-smoke the sausages once stuffed, and then re-freeze some of them... My husband read that we need to add cure salt to the sausage mixture if we want to cold smoke them, and we don't have to if we bring it up to temperature in the regular smoker. Would love any advice that you may have on thawing-smoking-refreezing, and on curing. Thank you in advance!
