Leviticus 2:2-4

New Century Version

² and then take it to Aaron’s sons, the priests. The priest must take a handful of the fine flour and oil and all the incense, and burn it on the altar as a memorial portion. It is an offering made by fire, and its smell is pleasing to the Lord. ³ The rest of the grain offering will belong to Aaron and the priests; it is a most holy part of the offerings made by fire to the Lord.

⁴ “‘If you bring a grain offering that was baked in the oven, it must be made from fine flour. It may be loaves made without yeast and mixed with oil, or it may be wafers made without yeast that have oil poured over them.
