@ppelaez A small amount of fat coming out is not all that uncommon. If you are using Walton’s casings they are pre-stuck, which means the have very small holes in them.
@mrobisr Thanks, I don’t know anything about cultures so thanks for the info. There was and still is a Cloverdale summer sausage called cervalot(sp) that has a tangy flavor to it that I don’t like, maybe its a cultured product.
