Master the hasselback knife technique and you’ll be able to serve up delicious, show-stopping dishes for every dinner party. Hasselbacking is actually very simple. It all began with a scrumptious potato dish first served in the 1700s at the Hasselbacken hotel in Stockholm, Sweden. They are sometimes called accordion potatoes. It’s all in the knife work — you cut a potato into very thin slices, stopping just before the bottom so they fan out but are still connected at the bottom.
