I found the following text here ( I would not describe it better)
"Dutch people do not eat their herring in a particularly civilized fashion. No, they love to make an amusing show and a big deal about the proper “Dutch way” to eat the little fishies. Trust me, it ain’t a pretty sight! Want to cut your herring into pretty pieces and eat it with a knife and fork? Dutch people serve herring with chopped raw onions and pickles, grab the fish by its slippery tail, cock back their heads and throw it down their gullets in one fell swoop! This act alone makes even the most humble Dutch person utterly proud and brimming with nationalistic delight!"

Have a nice day!
