Korean Clam Doenjang Soup

Starting the clams in cold water and bringing everything slowly to a boil draws flavor from the shells gradually rather than shocking them, building a stock base that grows richer as the temperature rises. The doenjang must be dissolved through a strainer rather than stirred in directly, because undissolved paste left in the soup creates a grainy texture and uneven seasoning. Since clams carry their own salt, the quantity of doenjang should be noticeably less than usual to prevent the finished soup from becoming over-salted; seasoning should always be adjusted at the end after tasting. Soft tofu cut into cubes adds a gentle, yielding protein bite, and Korean zucchini releases a quiet sweetness into the broth as it cooks through, softening the overall profile. Minced garlic introduced mid-cooking harmonizes with the fermented aroma of the doenjang without overpowering it. Scallion added in the final minute preserves its fresh, sharp note rather than turning limp and faded. No anchovy stock, no dried kelp, and no dashi of any kind is needed here, because the clams alone provide enough umami to build genuine depth. That restraint is what defines the soup: when the ingredients are kept simple, the natural sweetness and marine character of good clams come through cleanly, producing a broth that tastes more substantial than its short ingredient list suggests.
