Commentary for Leviticus 2:9

את אזכרתה ITS MEMORIAL PORTION — this is the “fistful” (קמץ) (cf. Rashi on v. 2).

The fistful. [Rashi knows this] because it is written above: “The kohein shall separate from the meal-offering,” and afterwards it is written: “its memorial portion and burn it on the altar...”

והרים, “the priest will lift off, etc.” just as this procedure mentioned in chapter 6,8 consists of a fistful of the priest’s three middle fingers, קומץ, so this is also what it means here, though the Torah does not mentions a quantity.

אשה ריח ניחוח, “an offering made by fire, of pleasant fragrance, for the Lord.” We find the same expression, i.e. ריח ניחוח in connection with the burnt offerings of birds (Leviticus1,9, and here it is to teach us that the acceptability and its welcome in the eyes of the Lord of an expensive offering or a low cost offering does not depend on the monetary value but on the attitude of the donor who presents it.
