Spinach
Spinacia oleracea
Spinach traveled one of the longest culinary journeys of any vegetable. Originating in ancient Persia (Iran), it moved east through Nepal to China during the Tang Dynasty (7th century), which is why its classical Chinese name 菠薐草 literally means 'Persian grass.' From China, it reached Korea, where it became so deeply integrated into the cuisine that most Koreans today consider it a native vegetable. The Korean name 시금치 may derive from the slightly tart (시큼한) taste of its red root. In Korean cooking, sigeumchi-namul is often the very first dish a new cook learns to make — its simplicity is deceptive, as mastering the 30-second blanch and the gentle hand-mixing with sesame oil teaches the foundational instincts of Korean cuisine. Historically, spinach was valued as a spring tonic after long winters of eating preserved and fermented foods, its cool nature believed to clear accumulated winter heat from the body.
New to Spinach?
Is this edible?
Yes! Spinach is one of the most universally eaten vegetables in Korea, appearing at nearly every meal as a side dish. Korean spinach is tender, sweet, and gentle — even children love it.
What does it taste like?
Similar to baby spinach but slightly sweeter and more tender, with none of the metallic aftertaste that mature Western spinach can have.
Where to buy
Any supermarket carries spinach. For the authentic Korean experience with red-tinged roots, check Korean grocery stores (H Mart, Lotte) or farmers markets. Baby spinach from any store works well too.
How to prepare
Wash thoroughly in several changes of water to remove sand. Blanch in boiling water for just 20-30 seconds (do not overcook!), then immediately plunge into ice water. Squeeze out excess water gently before seasoning.
Pro tip: Keep the red root attached — it is the sweetest, most nutritious part and adds beautiful color. The 30-second blanch is everything: even 10 seconds too long makes it mushy.

Key Compounds

Seasonal Availability
Korean spring spinach (March-May) is prized for its tender sweetness. Autumn spinach (October-November) develops deeper flavor from cool nights. Winter greenhouse spinach is available but less flavorful. The red-rooted Korean variety (포항초) is considered the finest.
Complementary Ingredients (궁합 재료)
The archetypal Korean pairing — nutty sesame oil amplifies spinach's mild sweetness and aids absorption of its fat-soluble vitamins
Spinach and tofu in doenjang soup is a classic combination; the cool spinach balances tofu's neutral nature
Together in bibimbap, their contrasting textures (silky vs. crunchy) create a complete vegetable harmony
Processing Methods (법제)
Brief blanching (under 30 seconds) reduces oxalic acid that can block calcium absorption while preserving nutrients and bright green color. Always rinse in cold water immediately after.
Consumption Tips by Health Goal
Eye health
Blanch lightly and dress with sesame oil to enhance absorption of fat-soluble lutein and beta-carotene. Eat regularly as a side dish.
Blood circulation
Consume the whole plant including the red root, which is richest in iron and flavonoids. The red root is traditionally considered the most medicinal part.
Digestion
Eat as a gentle side dish (namul) when recovering from illness. Its cool nature soothes an overheated stomach without burdening digestion.
Culinary Profile
Flavor
