Korean White Kimchi Clam Soup

Purged clams begin in cold water and are brought slowly to a boil so the rising temperature coaxes flavor from the shells gradually, building stock as they cook. Once the clams open they are lifted out, and the broth is strained through a fine sieve to eliminate any sand that clung to the shells. Chopped white kimchi is stirred into this clean clam stock, where its lactic sourness dissolves into the liquid and creates a flavor profile that reads simultaneously refreshing and layered. Adding the white kimchi brine as well deepens the acidity further, but its existing salt content demands a taste check before any additional seasoning goes in. Thick-cut tofu squares absorb the surrounding broth as they warm through, contributing a soft, substantial bite alongside their protein. A single cheongyang chili, sliced on the diagonal, introduces a measured sharpness that lifts the otherwise mild base without tilting the soup into heat-forward territory. Scallion should go in during the final thirty seconds of cooking rather than earlier; overcooked scallion loses the fresh, grassy aroma that punctuates the finish. Because this soup contains no gochugaru, the broth stays perfectly clear and pale, and the white kimchi sourness sharpens the clam umami from underneath rather than competing with it, producing a bowl that tastes more complex than its short ingredient list suggests.
