Maple Onion Soup

From the publication Inspired by Compliments brand. The editor asked Chef Ryan, who spent a year in Rotterdam, The Netherlands to submit some of his favourite soup van de dag or soup of the day that he created for the Dutch hotel he worked for. This is one of them. i don't know how authentic this is as a Dutch recipe, but I presume all the ingredients used in this one was not difficult to find.
