Every summer, tangled brambles across eastern and central North America sprout tiny, dark-purple jewels. Sweeter than a raspberry, less bracing than a blackberry, with a deep, almost wine-like complexity, this is the black raspberry, a native fruit that vanishes almost as quickly as it appears each year.
Although it grows wild from the Great Plains to Appalachia, few people have tasted, or can even identify, the black raspberries growing near their homes. Ask anyone who knows the berries, though, and you’ll hear the same refrain: Once you’ve tasted a ripe black raspberry, it’s hard to settle for anything else.
“Most people think, ‘That’s a really good raspberry,’ ” said Alan Bergo, author of The Forager Chef’s Book of Flora. “Then they taste it again, and it’s, ‘No, that might be the best raspberry.’ ”
Also known as the blackcap or Rubus occidentalis, the black raspberry is a close relative of the red raspberry but higher in sugar and lower in acid. Bursting with sweetness straight from the bush, its flavor concentrates when cooked into jams, syrups, and sauces. This true summer treat also shines in ice cream, creating a fuchsia-hued, tart-sweet custard beloved in the Northeast and Midwest.
Along with a blackcap ice cream, Bergo’s website, The Forager Chef, features recipes that showcase the berry’s strengths, with snappy vinegars, classic preserves, and glazes and gastriques that cut through the richness of duck and goose. “It’s a great entry-level wild fruit,” he said. “It’s trusty and reliable and easy to work with.”
Long before modern chefs praised black raspberries, the fruit had an established place in Indigenous foodways. For centuries, nations including the Iroquois, Anishinaabe, and Dakota collected and dried black raspberries each summer for use over the winter. Among the Lakota, the berries are used to make wóžapi, a sweet pudding, and wasná, a hearty mixture of dried meat, berries, and rendered fat, while the leaves are steeped to make medicinal teas for gut health and pregnancy pains.
“This is one of the super important berries to the Lakota people,” said Luke Black Elk, a chef and member of the Cheyenne River Lakota tribe. According to Black Elk, the Lakota language treats the blackcap as the default raspberry. “Our name for ‘raspberry’ is actually referencing black raspberry. We call red raspberry the word for black raspberry but with the modifier ‘red’ added.”
“We still have people who don’t know that black raspberries exist,” Linda, an ethnobotanist, said. “We’ve shown people blackcaps, and they’re like, ‘This grows in my backyard, but I always thought these were blackberries.’ ”
A big part of educating people about black raspberries is showing what they can do in the kitchen. At Sean Sherman’s Minneapolis restaurant, Indígena by Owamni, they’re brushed onto elk ribs as a summer glaze. Bakeries across rural Pennsylvania cook them into pies, baked puddings, and jams. At the U.S. Open in New York, the fruit lends its depth to the Honey Deuce, a cocktail of vodka, lemonade, melon balls, and black raspberry liqueur.
But even the most showstopping preparations can’t overcome blackcaps’ biggest drawback: There just aren’t enough of them. They bear fruit for just two to three weeks each summer, and harvesting such tiny, delicate berries is expensive and time-consuming.
Courtney Weber, a horticulturalist at Cornell University, has spent 20 years trying to breed a blackcap that avoids these pitfalls. According to Weber, they’ve been notoriously tough to grow because of limited genetic diversity. There is hope, though. In 2013, breeders cultivated a black raspberry that produced an early-summer harvest and a second crop in the early fall. It’s still a niche variety, but it hints at a future where blackcaps might be available beyond their brief window.
Until then, black raspberries remain a short-lived seasonal pleasure worth seeking out. Even if you can’t find them in a forest or farmers market, producers like Brecknock Orchard in Pennsylvania’s Lancaster County ship them frozen. Whether you’re working with fresh or frozen berries, you can transform them into a liqueur, simmer them into a sauce, bake them into a cake, or churn them into a lush ice cream. Their season may be brief, but their flavor lingers.
