Leviticus 6:15-16

15One of them shall take up from it a handful of the fine flour of the grain offering with its oil and all the incense that is on the grain offering, and he shall offer it up in smoke on the altar, a sweet and soothing aroma, as the memorial offering to the Lord.

16What is left of it Aaron and his sons are to eat. It shall be eaten as unleavened bread in a holy place; they are to eat it in the courtyard of the Tent of Meeting.
