The Most Common Mistakes in Sausage Making
Salt does several things to the ground sausage meat, the first being that it reduces the moisture content of the meat, which in turn increases its flavor. Secondly, meat is composed of tiny bundles of muscle fiber called fibrils, which, when exposed to salt, fray and bind to each other, creating a consistent texture in the sausage.

Milling and flour quality
Tempering is one of the most important parts of the flour milling process; the moisture content of the grain is increased by the addition of water and the grain sits for a period of time. This tempering process toughens the outer layers of the grain to minimise the production of bran powder during grinding, thus simplifying the physical ...
