Fiskefilet med remoulade is a Danish open-faced sandwich. It consists of a breaded and fried fish fillet (plaice, cod, flounder, sole, or any white fish) that's placed on a slice of buttered rye bread (rugbrød) with lettuce leaves.
The sandwich is topped with remoulade sauce and a lemon slice or wedge which can be squeezed for extra acidity, if desired. Due to the fact that the sandwich has many ingredients and eating it can be quite messy, it's often eaten with a knife and fork.
