Why is only a handful of the offering taken?

Leviticus 2:2 (ESV)

2 and bring it to Aaron’s sons the priests. And he shall take from it a handful of the fine flour and oil, with all of its frankincense, and the priest shall burn this as its memorial portion on the altar, a food offering with a pleasing aroma to the LORD.

The handful was probably representative for the entire offering.
