Most important part of the Hanukkah celebration?

Hanukkah celebrates the miracle of the oil that lasted for 8 days. Some things we usually do are:

-Light candles every night, with the blessings.

-Make latkes (potato pancakes) fried in oil.

-(Non-traditional): Give presents, but that is only in spirit of the other winter holidays. More traditional is the giving of Hanukkah gelt to children.

It should be noted that Hanukkah is NOT the most important holiday in Judaism, Rosh Hashanah and Yom Kippur are. And Dreidels are not the most important item.
