äggmacka
An äggmacka is a simple open-faced sandwich originating from Sweden. Its name directly translates to "egg sandwich" from Swedish. The primary components are a slice of bread, typically a hearty rye or crispbread, and a topping of hard-boiled or sometimes fried egg. The egg is usually sliced or mashed and then placed on the bread.
Common additions to an äggmacka include butter, mayonnaise, and various seasonings such as salt and pepper.
