Loganberries are a distinctive hybrid berry with the appearance of an elongated raspberry and a flavor that combines raspberry-like sweetness with the sharper character of blackberry. They are part of the Rubus group and are valued for their fiber, vitamin C, manganese, and naturally occurring polyphenols.
Fresh loganberries can be difficult to find because they are delicate and have a relatively short shelf life, but they can be enjoyed fresh, frozen, cooked, or made into jams, sauces, desserts, and drinks.
What Are Loganberries?
Loganberries are a hybrid fruit produced from a raspberry and American blackberry cross. Their botanical name is generally given as Rubus × loganobaccus. The fruit is typically elongated, dark red to deep reddish-purple when ripe, and has a soft, juicy texture with a distinctly tart flavor.
Unlike many common berries, loganberries are not simply a variety of raspberry or blackberry. They are a hybrid berry developed in California in the late 19th century and are now grown in several regions, including the United States, United Kingdom, and New Zealand.
Loganberries are particularly useful in cooking because their naturally sharp flavor works well with sugar, dairy, baked goods, and other fruits.
They also contain naturally occurring polyphenols. Research on Rubus berries has identified compounds such as ellagic acid, anthocyanins, and ellagitannins, although the exact levels vary according to species, cultivar, ripeness, and growing conditions.
