Small Side Of White Sauce

The food you're referring to is commonly known as "alfredo sauce." It's a rich and creamy white sauce made with butter, cream, and Parmesan cheese. It's often served as a side dish or used as a sauce for pasta.

Alfredo sauce is a classic Italian-American dish that was popularized in the United States in the mid-20th century. It's named after Alfredo Di Lelio, an Italian chef who is said to have created the dish in the early 1920s.

If you're looking to try alfredo sauce at a restaurant, you can usually find it on the menu as a side dish or as a sauce for pasta dishes like fettuccine or spaghetti. Some restaurants may also offer variations of the dish, such as vegetarian or gluten-free versions.

I hope that helps! Let me know if you have any other questions.
