In Sweden, making meatballs is a very social family affair. The more kids you can round up for the rolling the better, since a child's palm makes the perfect-size ball. When Fredrika Stjarne was young, she was a vegetarian and therefore a very unwilling participant! Now she has rejoined the world of carnivores and makes meatballs with her daughter and husband. She uses her father's recipe, with his secret ingredient (celery salt).
