Until the 20th century, shellfish were not eaten to any extent. This was partly due to the abundance of fish and the time involved in catching shellfish as compared to its nutritional value, as well as the fact that such food spoils rather quickly, even in a northern climate. However, prawns, crabs, and mussels have become quite popular, especially during summer. Lobster is, of course, popular, but restrictions on the catch (size and season) limit consumption. Lobster has become rather rare and expensive.
People gather for krabbefest, which translates to “crab party” feasts, either eating to cooked crabs from a fishmonger or cooking live crabs in a large pan. This is typically done outdoors, the style being rather rustic with only bread, mayonnaise, and wedges of lemon to go with the crab. Crabs are caught in pots by both professionals and amateurs, prawns are caught by small trawlers and sold ready cooked at the quays. It is popular to buy half a kilogram of pie prawns and to eat it on the quay, feeding the waste to seagulls. Beer or white wine is the normal accompaniment.
