Cleaning sausages in natural collagen casings can be very, very difficult.
However, this may not be done, reports the Zen channel “Arguments and Facts” with reference to the head of the Center for Economic and Analytical Research and IT Technologies of the Federal Scientific Center of Food Systems named after Gorbatov, Dmitry Gordeev.
As Gordeev explained, everything depends on what the shell is made of.
Sausages in natural collagen casings do not need to be peeled before cooking.
Moreover, such sausages can be eaten directly with the casing.
As for artificial and synthetic casings, they must meet the safety requirements specified in the relevant legislative documents.
According to the expert, this type of shell also does not need to be removed before cooking.
To make the film easy to remove, after cooking the sausages need to be doused with cold water.
