Groningen is a province in the North of the Netherlands, bordering the sea, and therefore prawns are often on the menu, like in prawn soup. There are several famous versions of "Groninger koek" (a form of spice cake) and also "Vegter's rolletjes" (rolls of biscuits, to be filled with whipped cream and often served for New Year) come from this province. Several liqueurs were brewed here, like Fladderak and Aniseed liqueur, by the Groningen based firm Hooghoudt. Marne's mustard is a typical mustard from Groningen. Alongside the straight canals you will find many potato fields and the potatoes are used as a basis for French fries and other potato products.
