Overview
Ginkgo nuts are the edible seeds of the ginkgo tree (Ginkgo biloba), a species with no close living relatives and a fossil record extending back roughly 270 million years [1]. Native to China, the tree has been cultivated for millennia and its seeds are used in East Asian cuisines as a starchy, subtly sweet ingredient with a soft, chewy texture. Raw ginkgo nuts contain toxic compounds and must be cooked before consumption.
Origin and history
The ginkgo tree is a living fossil, with fossilized leaves nearly identical to modern specimens dating to the Permian period [1]. It survived in refugia in China and was widely cultivated in temple gardens across East Asia. Ginkgo nuts appear in Chinese medicinal texts as early as the Song dynasty (960–1279 CE) and were introduced to Japan and Korea via Buddhist monastic networks. The tree was brought to Europe in the early 18th century and to North America in the late 18th century, though its culinary use outside East Asia remains limited. The seeds have been used in traditional Chinese medicine for respiratory and cognitive conditions, though clinical evidence for these uses is mixed [3].
Varieties and aliases
- Regional names include:
- Baeksu (Korean: 백수) — the nut itself
- Ginnan (Japanese: 銀杏) — the cooked nut
- Yinxing (Chinese: 银杏) — the tree and seed
- Maidenhair tree seed — English common name derived from the leaf shape
Culinary uses
Ginkgo nuts are typically shelled and cooked by boiling, roasting, or steaming. They are used in savory dishes, congee, and desserts. In Japanese cuisine, they appear in chawanmushi (savory egg custard) and are skewered and grilled as street food. In Korean cuisine, they are added to yeonnipbap (lotus leaf rice), samgyetang (ginseng chicken soup), and japchae (stir-fried glass noodles). In Chinese cuisine, they are used in buddha’s delight (a vegetarian dish) and sweet soups. The nuts have a mild, nutty flavor and a slightly gelatinous texture when cooked. They are often paired with chestnuts, jujubes, and glutinous rice in temple cuisine.
Cross-cuisine context
Ginkgo nuts have no direct analogue in Mexican cuisine or in the other LA-relevant cuisines listed on the platform. Their closest functional parallel might be the starchy, subtly sweet seeds of the chía (Salvia hispanica) or huauzontle (Chenopodium berlandieri) in Mesoamerican tradition, but these are prepared differently and lack the toxic raw state that requires cooking. In East Asian contexts, ginkgo nuts are sometimes grouped with chestnuts and lotus seeds as a category of starchy, textural ingredients used in both savory and sweet dishes.
Notes for cooks
- Raw ginkgo nuts contain 4’-O-methylpyridoxine (ginkgotoxin), which can cause seizures and other neurological symptoms if consumed in quantity. Always cook the nuts thoroughly before eating.
- The nuts have a thin, papery skin beneath the hard shell. After cooking, the skin can be rubbed off easily.
- Limit consumption to 5–10 nuts per serving. Larger amounts may cause adverse effects even when cooked.
