See actually Israel had an important offering the Golden sheave offering that had implications
of a spiritual harvest from a seed so dont miss out on what cains offering represented. Very profoundly important.
That why i like where it says "in the process of time" which implies the right time of the harvest.
I think the grain offerings could be made several different ways. In which this could represent our relationship, our giving back or involvement or better yet, interaction, with God.

(5) The Grain Offering was distinct from the Burnt Offering in that the Grain Offering allowed and even encouraged man’s contribution to the offering. The Burnt Offering allowed men to participate in the ceremony of the sacrifice, but not to add anything to the sacrifice. This can easily be understood in the light of the purpose of atonement and attaining divine favor. For sinful man to attempt to contribute to an atoning sacrifice would only defile that sacrifice. The Israelite could add nothing to that sacrifice which atoned for his sins, just as we can contribute nothing to the work of Christ, which atones for our sins.
The purpose of the Grain Offering is not atonement, but worship, acknowledgment of God’s divine provision of the needs of the Israelite for life itself. The Grain Offering praised God for His abundant supply of the “daily bread” of the Israelite. But while men do not contribute to their redemption, they do participate in the growing of the crops by which God sustains their life. Thus, the human element is present in the Grain Offering in a way that it is not in the Burnt Offering.
For example, the kind of grain that can be offered to God seems to be a matter of choice (although perhaps this was simply decided on the basis of what was available). The grain could be offered to God cooked or uncooked, and if cooked in a variety of ways. Verses 1-3 of Leviticus 2 prescribe the offering of uncooked grain, while verses 4-10 regulate the offering of that grain which is cooked in an oven (v. 4),[SUP]
41[/SUP] on a griddle (v. 5),[SUP]
42[/SUP] or in a pan (v. 7).[SUP]
43[/SUP] All of these options suggest freedom as to what form the offering can take, within the parameters God has set. Put in today’s terms, the offering could be that of flour, mixed with oil, of bread, of pancakes, of sweet rolls, or of donuts." Bob Deffinbaugh,
