What is the difference between baby Swiss and petit suisse cheese?

You're getting two very different cheeses mixed up!

* Baby Swiss is a type of Swiss cheese, also known as Emmental. It has the classic large holes and mild, nutty flavor. It's typically sold in smaller sizes, hence the name "baby."

* Petit Suisse is a type of cream cheese, typically made with cow's milk and often flavored with fruit. It's very different in texture and taste from Swiss cheese, and is usually enjoyed as a spread or dessert.

So, while they both have "Swiss" in their names, they are completely different cheeses with distinct flavors and textures.
