Amalia Eriksson was for a long time the only producer, but in time more bakers started working in the small city, manufacturing the peppermint rock to meet the rising demand. Today, a dozen bakeries in Gränna are making the peppermint rock and you can watch the manufacturing process take place. Boiling, pulling, kneading and twisting is made in the spirit of Amalia. In some of the boiler houses you can actually make your own peppermint rocks, it´s not as simple as it looks! To make the classic red and white peppermint rock, sugar, water and vinegar is mixed and then heated.
