Erwtensoep, pea soup, is the best-known winter dish in the Netherlands. It’s also called snert, the popular name for the very thick version. It is made with split dried peas slowly cooked with celeriac, celery stalks, leek, carrot, onion and potato, plus meat: a pork chop or bacon used during cooking and rookworst, the smoked sausage, sliced on top.
The soup is cooked for hours until the peas break down. It is said that a good snert is so thick a spoon can stand upright in the bowl. Many families prefer to eat it the next day, when it thickens even more.
In July 2018, the method of preparing the soup was added to the national inventory of intangible heritage.
Erwtensoep appears in the cold months in homes, cafés and restaurants, and is the food associated with afternoons of ice skating when the canals freeze and with winter walks. snert stalls commonly serve the soup at outdoor events in that season.
It is served hot, with rye bread (roggebrood) topped with smoked bacon or with regular bread and butter.
