Considered an essential part of the Finnish food culture, hernekeitto is a thick split pea soup cooked with pork that is traditionally prepared and served every Thursday throughout the country. Followed by a delicious pannukakku – an oven-baked pancake served with a big spoonful of berry jam, this well-rounded dish holds a special place in every Finn's heart.

The custom of indulging in such calorie-laden, homemade meals is rooted in the tradition of celebrating Laskiainen. This pagan holiday is related to Christian Lenten, dates back to the early Middle Ages, and marks the beginning of spring fasting, prior to which Finns feast on rich, fatty foods.

Only a remnant of religious practices, Laskiainen is nowadays celebrated as a secular family holiday during which people visit numerous fairs and other outdoor events where hernekeitto can be enjoyed fresh from the steaming pots simmering over bonfires.

Flavored with marjoram and black pepper, this hearty soup is topped with a dab of zingy mustard and served with rye bread.
