Meatloaf is a classic Swedish home-cooked meal. Bacon makes the meatloaf extra juicy and flavorful. The anchovies add the fifth basic flavor, umami, to the meatloaf, with their mild richness.
Meatloaf (or similar dishes with minced meat shaped into a loaf) is a dish with a long history and many variations around the world.
Meatloaf can be traced back to Rome in the 5th century AD, where minced meat (sometimes including entrails and brains) was used to make use of raw materials. During the Middle Ages in Europe, it was also common to combine minced meat with spices and other ingredients to create hearty dishes.
As you can see, meatloaf is a widely spread concept, although the names, ingredients and seasonings differ between different cultures!
