The mixture was covered with a
cotton cloth, and left to settle for 20 h at 0 °C, to let the mass homogenize
with the spices and additives. It was then fed through an H52 PAS
hydraulic piston-based sausage stuffer connected to a VAE-10 vacuum
system (Andher, Campo de Criptana, Spain), into synthetic collagen
skins, with a 38–40 mm diameter. Horseshoe-shaped salchichon
sausages were then tied off at 60 cm intervals.
