Spicy Korean Fish Stew (Maeuntang : 매운탕)

For Western-trained chefs, Korean maeuntang (spicy fish stew) represents a masterful study in balancing clean, aquatic sweetness with intense, layered heat. Presented by culinary authority Maangchi, this traditional recipe showcases how to construct a robust, aromatic broth that lifts fresh white-fleshed fish without masking its delicate flavour. It is an invaluable addition to any menu seeking to offer authentic, warming seafood dishes.

Constructing the Spicy Broth Base

The foundation of an exceptional maeuntang lies in its broth, which departs from the typical long-simmered Western fish stock. Instead, the technique relies on a rapid extraction of flavour. Chefs will learn the critical role of Korean radish (mu), which is layered at the bottom of the pot. As it simmers, the radish releases natural sugars that temper the heat and add a clean, refreshing sweetness to the liquid.

The heat profiles are built using a precise harmony of gochugaru (red pepper flakes) and gochujang (fermented red pepper paste), balanced with minced garlic and ginger. Unlike heavy stews, the body of this soup remains light and clear. This is achieved by skimming impurities diligently during the initial boil, ensuring the final presentation is vibrant red yet pristine, rather than cloudy or muddy.

Precision Timing and Finishing Aromatics

A common pitfall in rustic fish stews is overcooking the fish, causing the flesh to disintegrate and cloud the broth. Maangchi demonstrates the importance of timing: the sturdy radish and hard aromatics simmer first to establish the flavour base, while the fish—traditionally a whole, bone-in specimen like black sea bass—is added later. Cooking the fish on the bone is non-negotiable for professional applications, as it yields gelatin and deepens the soup's mouthfeel.

The final stages of execution require absolute precision. Delicate ingredients such as tofu, green chillies, and spring onions are added toward the end of the cooking process. Crucially, the stew is finished with fresh, peppery greens like crown daisy (ssukgat) or water dropwort (minari). These greens should only wilt in the residual heat just before service, providing a sharp, herbal contrast that cuts through the rich, spicy broth and cleanses the palate.
