Description/Taste
Koppa Kola leaves vary in size, depending on growing conditions and maturity at harvest, and average 6 to 12 centimeters in diameter. The leaves have a broad, oval, elliptic, or cordate shape with curved, serrated edges. Koppa Kola leaves feature a small notch around the stem and have a concave, cup-like curve, giving them a natural saucer shape. The leaves are dark green on the upper side and pale, muted green on the underside, with prominent yellow-green veining across the surface. The leaves also have a glossy, smooth, and papery-to-leathery consistency and are crisp and slightly chewy. When cooked, the leaves become softer and more tender. The stems are woody, fibrous, and firm. Koppa Kola leaves are aromatic and are said to release a sweet, savory, and curry-like scent. The leaves are edible raw or cooked and have a green, vegetal, subtly earthy, and slightly bitter taste.
Seasons/Availability
Koppa Kola leaves are available year-round.
Current Facts
Koppa Kola leaves, botanically classified as Polyscias scutellaria, are a tropical species belonging to the Araliaceae family. The leaves grow on an evergreen, upright, multi-branched shrub or small tree reaching 1 to 6 meters in height, and were historically a wild species that was later established in home gardens throughout Asia as an ornamental, culinary, and medicinal plant. The name Koppa Kola is the Sinhalese name for the species, the primary language spoken in Sri Lanka, where the leaves are sold in local markets for their nutritional properties. Koppa Kola leaves are also known by other regional names, including Platito in the Philippines, Daun Mangkokan in Indonesia, Pokok Puding Mangkok in Malaysia, Dinh Lang Dia in Vietnam, Krut Kra Thong in Thailand, and Shield Aralia, Plum Aralia, and Cup-Leaved Aralia in English. There are two main types of Koppa Kola leaves in markets: one with variegated green and white leaves and the other with solid green leaves. The solid green leaves, as seen in the photograph above, are the most common species and are valued for their versatility in a wide array of fresh and cooked savory culinary preparations. They are also a traditional medicinal green throughout South and Southeast Asia.
Nutritional Value
Koppa Kola leaves are a source of fiber to regulate digestion and contain vitamins A, C, and E. These vitamins support healthy organ function, strengthen the immune system, and protect cells from free radical damage. The leaves also provide varying amounts of minerals, including iron, calcium, and phosphorus. These minerals help the body produce the protein hemoglobin for oxygen transport throughout the bloodstream and for the formation of strong bones and teeth. In natural medicines, the leaves are sold dried as herbal tea. The roots, leaves, and bark are also used in various preparations as diuretics to lower blood pressure, to lessen symptoms of infections, and to help fight anemia. The species is thought to have anti-inflammatory, antiviral, and antibacterial properties. Topically, the leaves are boiled, and the liquid is applied to the hair to strengthen and stimulate growth, or the leaves are combined with other oils and ingredients and spread on the skin to soothe skin irritations and insect bites.
Applications
Koppa Kola leaves have a green, earthy, and subtly bitter taste suited for fresh and cooked preparations. Young, tender leaves can be eaten raw, but they are best cooked to develop a more pleasing aroma and flavor. Koppa Kola leaves are finely shredded into salads, chopped into sambol as a condiment, or cooked with aromatics and coconut in vegetable side dishes called mallum in Sri Lanka and keerai poriyal in South India. The leaves are also used for lalapan in Indonesia, a side dish of fresh vegetables mixed with spicy chili pastes, often served with rice. Koppa Kola leaves become fragrant when boiled, steamed, or stir-fried, and they are simmered into soups, stews, and curries. In Southeast Asia, Koppa Kola leaves are favored for egg curries and coconut curries. Gulai Daun Mangkokan is an Indonesian coconut milk-based curry cooked with chicken, tempeh, or fish. Koppa Kola leaves are also incorporated into herbal porridges in Sri Lanka as a medicinal dish. The leaves are used as edible wrappers for steamed food or as a snack when battered and fried. Koppa Kola leaves pair well with herbs like lemongrass, fenugreek, parsley, lime leaves, and bay leaves, aromatics including green chiles, onion, garlic, shallots, turmeric, and ginger, and lemon juice. Fresh leaves should be immediately used for the best quality and flavor, and will keep for a few days when stored in the refrigerator’s crisper drawer. They can also be dried for extended use.
Ethnic/Cultural Info
Koppa Kola leaves are known as Daun Mangkokan in Indonesia, a name that roughly translates to “bowl leaf.” The species was traditionally used as an edible serving vessel for its large size, rounded, cup-like shape, and hardiness, being tear-resistant. The leaves are used throughout Indonesia, fresh or steamed, and heating them is believed to enhance the species’ distinct sweet, spicy, and savory scent. Mangkokan is also considered an aesthetically pleasing addition to plates and is customarily used to wrap fish dishes, especially sardines, to mask their odor. The leaves are also used as wrappers for other meat preparations or eaten with rice. Another well-known preparation using Mangkokan leaves is pindang tofu, an Indonesian dish in which tofu is cooked in an aromatic broth. This cooking method yields a soft, tender texture, and the tofu is later steamed in the leaves for enhanced flavor.
Geography/History
Koppa Kola leaves are native to tropical regions of South and Southeast Asia, and the Pacific Islands, and have been growing wild since ancient times. The origins of the species are sometimes debated among historians and scientists, with some noting that it may also be native to tropical regions of America and Africa. Despite these debated origins, Koppa Kola leaves are found in warm, humid, low-altitude regions up to 800 meters in elevation and have spread from the wild, naturalizing in home gardens, along roadsides, in forests, and lining village fences. Koppa Kola leaves are widely grown as ornamental plants and are commercially grown on a small scale for garden planting. Today, Koppa Kola leaves are found in their native growing regions and in other tropical regions worldwide, and are sold in local markets. The Koppa Kola leaves featured in the photograph above were sourced through the Saturday Good Market in Colombo, Sri Lanka.
