Bottled Parmesan cheese
That green bottle of Parmesan cheese we all have in our pantries holds a rather unusual secret. Authentic Parmesan cheese should only be made of milk, rennet, and salt, the rest is time, as cheese ages to gain its delectable flavor and aromas.
Bottled ‘Parmesan’ cheese is not parmesan, and it’s not only cheese either. There’s lots of cellulose in that bottle; it’s used as a filler. And if the component doesn’t ring a bell yet, it’s also known as wood pulp.
