This is one of those mitzvot. We might think that honey should be put on a korban in order to enhance it. We'd be wrongwith that logic. This is so for all mitzvot, not just the ones that defy our logic. The Sefer HaChinuch explains that many of the procedures of the Mikdash are things that people can relate to in a positive way from their everyday life.
People salt their food.
This is done to enhance flavor and sometimes as a preservative. The Chinuch adds that just as salt helps maintain and prolong the life of food, and prevents spoiling, so too does a korban maintain andprolong a preson's life and helps prevent spoilage. Our table is like the Mizbei'ach. A famous saying with many different manifestations. We salt our HaMotzi bread because we are expected to add an element of spirituality to an otherwise very mundane act of eating.
