text_A: In Russia, Ukraine and other former Soviet states, a very similar product is called "doktorskaya kolbasa" (, lit. "doctor's sausage"). However, this product is normally made from a mixture of beef and pork (sometimes beef and lamb or chicken for religious reasons), and does not include pieces of fat or myrtle; mortadella-style sausages with pieces of fat are called "lubitelskaya" and "stolichnaya". Instead, it is flavoured with just cardamom, sometimes coriander and nutmeg, and also traditionally contains eggs and milk, which are a key ingredient in traditional mortadella. Unlike mortadella, "doktorskaya kolbasa" contains higher amounts of fat and is high in proteins.
text_B: Would someone with a crippling allergy to dairy products be safer choosing mortadella over doctor's sausage (assuming that a choice had to be made, and they couldn't ascertain the ingredients beforehand, having to rely on probabilities)?
NO.
