in the casings is preferable to me, and # of sausages works best for my understanding..
In the casings is what I use most often; and the number of sausages certainly would be the most simple for me also.
Just pounds of sausage and then I decide if I want to do bulk or casings.
casings and # of sausage (maybe weight in parenthesis?)(ps, I totally spelled that wrong,b ut you get the idea.)
If I buy it in casings, I always remove them. I prefer to work with weight, but both measurements might be a good idea.
I am not a fan of casings! I prefer weight.
