So funny: an English-speaking person messing up perfectly good Dutch! The plural of "fritkot" is "fritkoten" not "fritkots". Kots is dutch for vomit and as a good belgian I can promise you you'll never get sick from Belgian frieten. Unless you eat too many which is perfectly possible ;-)
That being said: thanks for advertising for our great frieten! Eat them with beef stew (stoofvlees) or mussels (mosselen). And of course don't forget: they only taste their best if combined with one of our 1000+ beers!
