Swedish Yellow Pea Soup (Rtsoppa) is a traditional Swedish dish made with yellow split peas, vegetables, and smoked pork. It is a hearty and flavorful soup that is often enjoyed during the colder months. The yellow split peas are simmered with onions, carrots, and celery until they are tender and creamy. The smoked pork adds a rich and smoky flavor to the soup. It is typically served with a dollop of mustard and accompanied by crispbread or rye bread.
