Ethiopian Kale
Brassica carinata
Ethiopian Kale (Brassica carinata), known as yakina or gommen in Ethiopia, is a robust, heat-tolerant leafy green that has sustained communities in the Horn of Africa for millennia. A unique hybrid species derived from the crossing of cabbage (Brassica oleracea) and mustard (Brassica nigra), it combines the best traits of both parents: the tender, fleshy leaves of cabbage with the peppery zip of mustard. In the highlands of Ethiopia, where it is the most important leaf vegetable, Ethiopian kale is to daily cooking what spinach is to the Western world.
• The only Brassica species that originated in Africa — all others come from Europe or Asia
• A natural allotetraploid hybrid between Brassica nigra (black mustard) and Brassica oleracea (cabbage)
• Known as "yakina" (Amharic), "gommen" (Ethiopian), and "African mustard" in English
• Both the leaves and young flowering stems are eaten
• Remarkably heat-tolerant for a Brassica, thriving where European kales would bolt immediately
Taxonomie
• Originated in the Ethiopian and Eritrean highlands at elevations of 1,500 to 2,600 meters
• Has been cultivated in Ethiopia for over 4,000 years, making it one of the oldest African domesticated crops
• Remains the single most important leaf vegetable in Ethiopian cuisine
• Also grown in East Africa, particularly in Kenya, Tanzania, and Uganda
• Introduced to other tropical highland regions in the 20th century
• Relatively unknown outside Africa despite its nutritional importance
• Genetic studies confirm its hybrid origin from B. nigra and B. oleracea
• Adapted to the unique cool-but-tropical conditions of the Ethiopian highlands
Leaves:
• Large, broad, ovate to oblong, 15 to 40 cm long and 8 to 20 cm wide
• Dark blue-green with a waxy bloom, thick and fleshy
• Margins smooth to slightly toothed or wavy
• Tender when young, becoming tougher with age
• Form a loose rosette before bolting
Flowering stems:
• Tall, upright, branching racemes of bright yellow flowers
• Young flower stalks are tender and eaten like broccoli raab
• Flower buds are also harvested and cooked
Flowers:
• Typical Brassica flowers with four bright yellow petals, 1 to 2 cm across
• Self-pollinating but also insect-pollinated
Seeds:
• Small, dark brown to black, produced in slender pods (siliques)
• Seeds contain 25 to 35% oil and are pressed for cooking oil in Ethiopia
• Thrives at elevations of 1,500 to 2,600 meters
• Prefers temperatures between 15 and 25°C — cool for the tropics but warm for most Brassicas
• More heat-tolerant than European kales and cabbages
• Requires well-drained, fertile soils with pH 6.0 to 7.5
• Grows best in full sun
• Requires consistent moisture for optimal leaf production
• Bolts rapidly in very hot conditions or long days
• Relatively resistant to common Brassica pests and diseases
• Responds well to organic fertilizers and compost
• Fast-growing, reaching harvestable size in 30 to 45 days
• Very high in vitamin A (beta-carotene), providing well over 100% of daily needs per 100 g
• Excellent source of vitamin C
• Rich in calcium, iron, and potassium
• Good source of dietary fiber and protein (3 to 5 g per 100 g)
• Contains glucosinolates, sulfur compounds with potential anti-cancer properties
• Provides folate and vitamin K
• Higher in most nutrients than common cabbage or kale
• Low in calories, approximately 25 to 35 kcal per 100 g
• Seeds are rich in erucic acid and used for cooking oil
• Direct-sow seeds in prepared beds, 0.5 to 1 cm deep
• Thin seedlings to 15 to 25 cm apart for leaf production
• Can be broadcast-sown for baby leaf harvest
• Germination in 5 to 10 days at 15 to 25°C
• Begin harvesting outer leaves 30 to 40 days after sowing
• Harvest progressively, taking outer leaves and allowing center growth to continue
• Young flower stalks can be harvested like broccoli raab at 60 to 80 days
• Apply compost or well-rotted manure before planting
• Regular watering keeps leaves tender and prevents premature bolting
• Succession plant every 2 to 3 weeks for continuous harvest
Leaves:
• The primary ingredient in "yakina alicha" (Ethiopian kale stew)
• Cooked with onions, garlic, and niter kibbeh (Ethiopian spiced butter)
• Used in "gomen" (kale dish) served with injera bread
• Sautéed, boiled, or steamed as a daily side dish
• Combined with legumes in traditional preparations
• Sometimes fermented
Young flower stems:
• Cooked and eaten like broccoli raab or rapini
• Used in stir-fries and stews
Seeds:
• Pressed for cooking oil in rural Ethiopia
• Sometimes ground and used as a condiment

Ethiopian Kale is living proof that Africa contributed its own species to the Brassica family — it is the only member of the genus that evolved on the continent. While the rest of the world's kales and cabbages come from the Mediterranean or Asia, this singular African Brassica developed its own unique character in the Ethiopian highlands, creating a vegetable that tastes like no other leafy green on Earth.
