The Hebrew noun minkhah (מִנְחָה) is used 211 times in the Masoretic Text of the Hebrew Bible with the first instances being the minkhah offered by both Cain and Abel in Genesis 4:3-5.
In the King James Version of 1611 this was rendered as "meat offerings", e.g. in Exodus 29:41, since at the time the King James Version was written, meat referred to food in general rather than the flesh of animals in particular.
The quintessential "gift offering" was one of grain (not just high quality flour), frankincense, and oil.
According to Menachos 76a ten such cakes of bread had to be made for each offering (except for the meal-offering of fine flour).
[1] A portion of this was then burnt on the altar, along with the frankincense, while the remainder was allocated to the priests, who were to eat it within the sanctuary.
