Everything we all thought we knew about Parmesan cheese is actually a lie.
The delicious nutty-flavored Italian cuisine accompaniment has been a staple in pantries across the globe and it's almost impossible to imagine pasta without the sharp cheese as a topping. So it only made sense for people to be worked up after some interesting information about Parmesan started making rounds online.
It's been recently reported by multiple sources that there's an ingredient in the versatile cheese that could change the way some people eat it. This fact may come as a shock to you but it isn't really a deep-dark secret that manufacturers were trying to keep from the public.
Apparently, Parmigiano-Reggiano cheese is not vegetarian.
Among the three ingredients used to make Parmesan cheese is rennet, an active enzyme (chymosin) that is found in the lining of a calf's stomach. This agent is important for the curdling process in cheesemaking. Since Parmigiano-Reggiano holds a Protected Designation of Origin status, the traditional recipe cannot be altered and the rennet has to be included.
