Amaranth Greens (Bireum)
Amaranthus mangostanus
Bireum — amaranth greens — has been a summer staple in Korean kitchens for centuries. The Donguibogam specifically notes its value as a cooling food during the hot months, and Korean grandmothers have long served bireum-namul as a way to beat the summer heat. Amaranth grows prolifically in warm weather and was historically one of the most accessible vegetables for common people, thriving even in poor soil and requiring minimal care. The red-stemmed variety was particularly valued in folk medicine. Interestingly, while Western health food trends have recently discovered amaranth as a superfood grain, Koreans have quietly been eating the leaves as a humble summer side dish for generations.
New to Amaranth Greens (Bireum)?
Is this edible?
Yes! If you've ever had callaloo in Caribbean cuisine, you've eaten a close relative. Amaranth greens are eaten worldwide.
What does it taste like?
Very mild, like a softer, gentler version of spinach. Almost no bitterness. One of the most beginner-friendly Korean greens.
Where to buy
Check Asian grocery stores or Caribbean markets (where it's sold as callaloo). Some farmers' markets carry amaranth greens in summer. You can also easily grow it.
How to prepare
Wash well, trim tough stem ends. Blanch the whole stems and leaves for just 20-30 seconds. Shock in cold water, squeeze dry, cut into bite-sized pieces, and season.
Pro tip: Bireum is one of the rare Korean namul that works beautifully with doenjang dressing rather than the usual soy sauce. The earthy doenjang complements the mild greens perfectly.

Seasonal Availability
A quintessential summer green, thriving in hot weather (June-August). Young shoots are most tender. Rarely dried — best enjoyed fresh in season.
Complementary Ingredients (궁합 재료)
Processing Methods (법제)
Brief blanching (20-30 seconds) wilts the tender leaves and stems perfectly. Over-blanching turns them mushy — bireum cooks very fast.
Consumption Tips by Health Goal
