As I explained in the post about what is Swedish on our national day, what is really Swedish is to eat crisp-bread with fish roe spread. It's our peanut-butter & jelly, or marmite on toast if you will. To make it eggstra (see what I did there? I should be punished for that.) yummy, we'll put the fish egg paste on slices of hardboiled eggs. This is where the beloved brand of fish roe paste called Kalles Kaviar comes to the rescue with a handy hard-boiled egg app. Set the egg-timer and the app will make you a perfect playlist for the perfect egg. 'Cuz that's another very Swedish thing, we're so bleedin' edge all the time we no longer use mechanical egg-timers. True story.
