Where did the term Au Jus come from?

The term "Au Jus" is a French phrase meaning "in its juice." It refers to a type of sauce or gravy made from the natural juices of the meat being cooked.

Here's a breakdown of the origins:

* "Au" is a French preposition meaning "in" or "to."

* "Jus" is the French word for "juice."
