John Gill Commentary Leviticus 2:16

"And the priest shall burn the memorial of it, part of the bruised grain thereof, and part of the oil thereof, with all the frankincense thereof: it is an offering made by fire unto Jehovah." — Leviticus 2:16 (ASV)

The priest shall burn the memorial of it
That which is taken out of it for a memorial, the same with the handful of fine flour and cakes of the meat offering:

part of the beaten corn thereof ;
or that which was ground in a mill:

and part of the oil thereof, with all the frankincense thereof ;
as was done in the other meat offerings:

it is an offering made by fire unto the Lord ,
see (Leviticus 2:2) .
