Korean Shepherd's Purse Soup

Naengi is a cruciferous plant gathered from paddies, field edges, and roadsides in early spring, and both the root and the leaves are used. The root contributes an earthy, mineral fragrance and the leaves carry a slightly bitter green quality that together define the soup's character. The stock is made from dried anchovies and kelp simmered and strained, providing a clean umami base. Doenjang is dissolved through a mesh strainer rather than stirred directly into the pot, which keeps the broth clear rather than murky while still delivering the fermented soybean depth. Diced tofu simmers in the seasoned broth until warmed through. Naengi goes in during the final two to three minutes of cooking: longer exposure to heat breaks down the aromatic compounds in the herb and erases the spring fragrance that makes the soup worth making in the first place. The pairing of naengi's earthy bitterness with the fermented depth of the doenjang and the clean mineral tone of the anchovy stock produces a flavor that is distinctly seasonal and difficult to replicate outside of spring. Soup soy sauce, salt, and a small amount of garlic complete the seasoning. In Korean food culture, naengi-guk on the table is understood as one of the clearest signs that winter is finished.
