Most Americans are not familiar with the lingonberry, which grows wild in Scandinavian forests and in Northern Canada, and flourishes in the summer during the midnight sun. They are small firm berries with a slightly sweet and sour flavor. Lingonberry Preserve is a traditional Scandinavian food with an exotic flavor. Hafi Lingonberry Preserve is made in Sweden and is a delicious alternative to tart jams and preserves, such as currant or raspberry.
