What is a type of sauce that never put on pasta?

There's no definitive answer to this question! Pasta is incredibly versatile, and people enjoy it with a wide variety of sauces.

It's more about personal preference and what flavors you like to combine.

Here are some possibilities:

* Sweet sauces: While you might find some sweet sauces used on pasta (like a fruit sauce or a caramel sauce), they are not traditionally used.

* Very spicy sauces: Some people find very spicy sauces overwhelming on pasta.

* Very thick sauces: A thick sauce like a gravy might be too heavy for pasta.

Ultimately, what you put on your pasta is up to you! If you enjoy it, then it's a good sauce.
