A bit like doughnuts but better.
I am not a fan of doughnuts.
They say this was first the doughnuts was invented by this idea.

Since they say the Netherlands is based on the jewish orthodox religion I guess this fried ball is a part of the old Hanukkah food. In the last week of the year you will find stalls selling them with us.
We eat them on New Year's eve. That is the celebration. There are no other ideas behind it. It just became a custom.
