Spread the bread generously with cheese sauce. We put pieces of herring fillet on top, and add grainy mustard (this is for those who like it sharper!) optionally, and a thin slice of radish. I serve it festively, so I will line the dish with lettuce leaves, put each leaf on toast and sprinkle with a little green onion and small sprigs of dill. Since we have the year of the white mouse, we put a mouse from an egg with ears and a nose made of radish, a little pepper, peas and a tail – stalk from dill on a plate. The food is ready! Festive, beautiful.
