Leviticus 2:11

But no mincha which thou offerest to the Lord shalt thou make with leaven; for neither leaven nor honey mayest thou offer as an oblation before the Lord.

leaven the agent that causes bread to rise honey also a leavening agent. Many people have said that the word honey here, and in every occurrence of “a land flowing with milk and honey” [e.g., Exodus 3:8], denotes honey made from dates. Grounds for their interpretation can be found in Ezra’s book [II Chronicles 31:5].

NO MEAL-OFFERING, WHICH YE SHALL BRING UNTO THE ETERNAL, SHALL BE MADE WITH LEAVEN. Here He prohibited the bringing of a meal-offering in leaven form. After that He said, Ye shall not ‘thaktiru’ (cause to ascend in fumes) either any leaven or honey, in order to prohibit the leavening of the handful and burning it upon the altar, this being included in the expression ye shall not cause to ascend in fumes … All terms of haktarah are expressions of burning aromatics, for druggists say 12:4. that honey would have been appropriate for the incense,. For since honey is mentioned in the verse, and honey would have improved the scent of the incense, Scripture uses a term which is applicable to the burning of aromatics. but the Torah prohibited it. Scripture states any of it in order to prohibit [leaven or honey] even as a part of it, that is to say, even in one half of the handful. Similarly, one is liable to the punishment of stripes for mixing [leaven or honey with the handful in such a way that it is not recognized], because Scripture included it in saying, for ye shall not cause to ascend in fumes ‘any’ leaven or ‘any’ honey, as is explained in Tractate Menachoth and in Tractate Pesachim.
The reason why Scripture mentions here minchah hi [hei-vav-alef, which is the masculine third person pronoun], but it is read hi [hei-yod-alef, which is the equivalent feminine pronoun]. Ramban intends to explain why it is written in the masculine when the word minchah is in the feminine, and hence Scripture should have written minchah hi. [in the feminine] while it is written hu [in the masculine], and similarly in all places, [will be understood] from the section, Behold, I send a messenger before thee. (Abusaula). The implication is that here too one gender is included in the other, namely, the feminine hi in the masculine hu, as explained in the text. So also ‘ha’ishah hahi’ (that woman) [is written hahu in the masculine, while it is read hahi in the feminine], because the feminine is potentially included in the masculine.
It is possible that the reason why we are forbidden to bring leaven and honey [upon the altar] is as the Rabbi [Moshe ben Maimon] states in the Moreh Nebuchim, where he says that he found it written in their books that the custom among the idolaters was to offer all their meal-offerings …

וכל דבש, honey gained from trees. Dates are also called “honey.”

כי כל שאור וכל דבש לא תקטירו, “for you must not let go up in smoke anything leavened or any honey.” The reason was that G–d had said that every offering had to be accompanied with a certain amount of salt (Leviticus 2,13) and the two ingredients mentioned here are not compatible with salt.
