Thimbleberries (Rubus parviflorus) are a native North American fruit that are edible. Closely related to raspberries and blackberries within the Rubus genus, their edibility makes them a popular wild edible.
Identifying Thimbleberries
Thimbleberry plants are deciduous shrubs, typically growing between 3 and 8 feet tall, with thornless stems that can spread through underground rhizomes, often forming dense clumps. Their large, maple-leaf-shaped leaves, ranging from 4 to 11 inches across, feature five lobes, toothed edges, and are notably soft and fuzzy to the touch with a pale green, hairy underside.
In spring and early summer, the plants produce showy white flowers, sometimes with a pinkish tint, typically 1.5 to 2 inches in diameter, with five delicate petals and a prominent center. The fruit is an aggregate of small, red, opaque drupelets, resembling a raspberry but often flatter and more dome-shaped, and it has a hollow core when picked. The berries ripen from white or pink to a bright red, and their skin is thin, fuzzy, and delicate.
Taste and Culinary Uses
Thimbleberries have a unique sweet and tart flavor, often described as having a delicate, musky, or honeyed aftertaste. Some find their taste similar to a raspberry, but with a distinct nuance. Their texture is soft, almost velvety, though the fruit contains many small, crunchy seeds. Due to their delicate nature and short shelf life, thimbleberries are not typically sold commercially.
They are excellent for making jams, jellies, pies, and other baked goods such as cobblers and muffins. Thimbleberries can also be incorporated into sauces for savory dishes like roasted meats, or blended into vinaigrettes. For longer preservation, they can be juiced for cocktails or wine, or pressed and dried into fruit leather.
Nutritional Profile
Thimbleberries contain vitamins and minerals. They are a source of vitamins A and C, both antioxidants. These berries also contain trace amounts of minerals such as potassium, calcium, and iron. A 100-gram serving contains approximately 47 calories.
Harvesting and Storage
Thimbleberries are typically ready for harvest from mid-June to late August. Ripe berries detach easily and turn from pink to a brilliant red. Due to their delicate nature, gentle handling is necessary during harvesting; use a wide container to prevent bruising.
Once picked, thimbleberries have a short shelf life, lasting only a few days in the refrigerator. Refrigeration is recommended, but avoid washing them until just before use to prevent spoilage. For longer-term preservation, they can be frozen, canned, or dehydrated.
