Search “borage” in English and you get a garnish: small blue star-shaped flowers, a handful of young leaves with a faint cucumber taste, the kind of thing floated in a Pimm’s Cup or frozen into an ice cube for a summer photo. Order borraja on a menu in Pamplona or Tudela and none of that arrives. What shows up is a hot plate of pale, peeled stalks, usually boiled with chunks of potato, sometimes finished with a garlic and ham sofrito. It is the same species, Borago officinalis, but Navarra built its entire culinary relationship with the plant around a part almost no English-language source ever mentions.
That gap matters for more than trivia. A visitor who has read about “borage” as a delicate salad herb and then sees borraja listed as a hearty winter vegetable dish will assume it’s a mistranslation, a different plant, or a strange regional joke. It’s none of those. The confusion comes from two culinary traditions harvesting different organs of one plant: the flower and young leaf internationally, the mature stalk in Navarra, Aragón, and La Rioja. Missing that distinction means missing one of the Ribera del Ebro’s genuine, still-working food traditions, not a novelty dish invented for tourists.
This account draws on Spanish- and English-language botanical references cross-checked against each other, direct reporting from Navarra’s own Ribera growers by the established Spanish food and travel publisher Guía Repsol, the municipal winter vegetable programming published by the Ayuntamiento de Tudela, and a currently operating Tudela restaurant’s own menu, verified directly rather than assumed from a passing mention.
The Part of the Plant Is the Whole Story
Borage’s international culinary reputation rests on its leaves and flowers. The young leaves carry a mild cucumber flavor and get used raw in salads or as a garnish. The small, intensely blue, star-shaped flowers show up scattered over desserts, frozen into ice cubes, or floated on cocktails, most famously the Pimm’s Cup. Both parts are eaten fresh and uncooked, and both are treated as an accent rather than a meal.
Borraja in Navarra, Aragón, and La Rioja is a different dish built from a different organ entirely: the thick, mature stalk of the same plant. That stalk is fibrous and covered in small bristles, which is why the first and non-negotiable step in preparing it is de-stringing it by hand, peeling away the tough outer strings the same way you’d string celery, before it ever touches a pot. Once peeled, the stalk is boiled, usually cut into pieces and cooked together with chunks of potato. From there it might be finished with a sofrito of garlic and diced serrano ham fried in olive oil, folded into a menestra alongside the region’s other vegetables, stirred into a pot of pochas as a home cook’s variation on the region’s classic bean dish, added to soups and broths, sautéed with young garlic shoots and wild mushrooms, or served as a side to fish and meat. None of that is raw, and none of it is a garnish. It is a substantial cooked vegetable course.
Other parts of Europe do cook with borage too. Germany uses the leaves in the cold sauce grüne Soße, Liguria fills ravioli with it, and it appears in soups on Crete. None of those traditions, though, center on the mature stalk the way Navarra’s does. The stalk preparation isn’t a variation on the international norm. It’s closer to a separate culinary tradition that happens to share a botanical name with the garnish herb.
A Mediterranean Plant That Found a Narrow Spanish Niche
Borago officinalis is not native to Navarra, or to Spain at all. Botanical references trace its origin to Syria, Lebanon, and Egypt, from where it spread and naturalized across the wider Mediterranean, Asia Minor, western Europe, North Africa, and parts of South America. Somewhere in that long spread, two separate culinary habits formed around it: one that kept to the leaf and flower, which is the version most of the world inherited, and one, concentrated in the Ebro valley, that developed around the stalk instead. Both habits are old. Neither is a modern invention layered onto the other.
The stalk and the leaf share the same basic nutritional character. Both are credited with meaningful vitamin C and B content along with iron and calcium, standard for a leafy vegetable in this plant family, though no single authoritative nutritional dataset exists specifically for the cooked Navarra preparation. What’s more useful to a visitor than a nutrition panel is the plain fact of the plant’s obscurity: Spanish-language food writing about borraja consistently describes it as unrecognized in most of the country, not just abroad. A vegetable this narrowly regional, still commercially grown and still served in ordinary restaurants rather than only revived for festivals, is a more reliable sign of a living food tradition than almost anything with wider name recognition would be.
Where It Grows: The Ribera’s Winter Huerta
Navarra’s borraja comes almost entirely from the Ribera, the irrigated stretch of land along the Ebro in the south of the region, centered on Tudela. It grows alongside the Ribera’s other prized winter crops: cardo, alcachofa de Tudela, achicoria, and cogollos, the small prized lettuce hearts of the area. Growers in the region describe this cluster collectively as the “verduras del hielo,” the frost vegetables, because a cold snap slows their growth and concentrates their sweetness instead of damaging them, a tolerance the more fragile artichoke doesn’t share once temperatures drop much below freezing.
The planting and harvest calendar runs on a winter cycle. Sowing generally begins around August, and the crop is harvested through the winter into early spring, putting borraja on Ribera tables well before the region’s spring-harvested white asparagus and running roughly parallel to cardo and artichoke season. Beyond Navarra, the same crop is grown commercially across the wider Ebro valley in Aragón and La Rioja, with growers there working two named commercial varieties, Movera for spring and summer sowing and Flor Blanca for autumn and winter sowing, and Navarra notable for feeding both its fresh market and a working canning and preserves industry side by side.
Outside that cluster of regions, borraja is genuinely obscure, and not only to foreign visitors. Spanish-language sources describing the vegetable routinely note that it goes largely unrecognized in other parts of Spain itself. This is not an international blind spot. It’s a narrowly regional food that happens to also confuse English speakers for a second, unrelated reason.
Inverdura: Where the Ribera Puts Its Winter Vegetables on Display
Tudela has an institutional answer to the fact that its winter vegetables rarely travel. Inverdura, organized by the Federación de Sociedades Gastronómicas El Hortelano together with the Ayuntamiento de Tudela, runs roughly from late November through February and builds an entire program around the Ribera’s cold-season huerta. Themed dinners, tastings, a pincho competition, guided historic routes through the city, and special restaurant menus all center on the same short list of vegetables: cardo, alcachofa de Tudela, borraja, and cogollos.
Because Inverdura runs in winter, it does not overlap with San Fermín week in July, and this article won’t strain that connection. The honest link is regional, not festival-specific: Inverdura is the clearest present-day evidence that borraja is a living, actively celebrated part of Ribera identity rather than a dish that survives only in old cookbooks. It sits alongside Tudela’s separate spring event, the Fiestas de la Verdura, which centers on a public menestra-cooking competition judged against the region’s own four-vegetable standard rather than on borraja specifically.
Where to Actually Find It on a Plate
Restaurante Iruña in Tudela, founded in 1940 and located beside the Plaza de los Fueros, serves borage croquettes, croquetas de borraja, as a starter, and the dish drew specific praise in regional press coverage for its creaminess in 2025. It’s a straightforward, current example of the ingredient showing up in an ordinary Tudela restaurant rather than as a festival-only curiosity, and it illustrates how kitchens have started adapting the traditional stalk into modern formats like croquettes alongside the classic boiled-with-potato preparation.
The more traditional route to trying borraja is simpler and cheaper: order it wherever a Ribera-focused restaurant lists a seasonal verdura de la Ribera menu, particularly between late autumn and early spring, and expect potato as the default companion. Outside that window, or outside the Ribera itself, it becomes considerably harder to find on a menu at all, which is consistent with everything else about the vegetable: a genuine regional specialty, not a manufactured one.
Frequently Asked Questions
What is borraja?
Borraja is the Spanish name for Borago officinalis, the same plant known in English as borage. In Navarra, Aragón, and La Rioja, the name specifically refers to a cooked vegetable dish made from the plant’s peeled, boiled stalk, not the leaves or flowers most English-language sources describe.
Is borraja the same as borage?
Botanically, yes, they are the identical species. Culinarily, they diverge sharply: English-language “borage” almost always means the raw young leaf or the blue flower used as a garnish, while Navarra’s borraja is the mature stalk, de-stringed and boiled, served as a hot vegetable course rather than a garnish.
How do you eat borraja?
The stalk is peeled to remove its tough outer strings, then boiled, most commonly with chunks of potato. From there it’s often finished with a garlic and serrano ham sofrito, worked into a menestra, added to soups, sautéed with young garlic shoots and wild mushrooms, or served alongside fish or meat.
Where does Navarra’s borraja come from?
Nearly all of it comes from the Ribera, the irrigated region along the Ebro around Tudela, where it grows alongside cardo, alcachofa de Tudela, and cogollos as one of the area’s “verduras del hielo,” or frost vegetables, planted around August and harvested through winter into early spring.
