Simple Soybean Paste SoupDoenjangguk

There is a specific doenjangguk that every Korean knows as home. Not restaurant doenjang jjigae — that's thicker, richer, with more ingredients. Doenjangguk is the daily soup: lighter, cleaner, quicker. It appears at the table in the morning, at lunch, sometimes at dinner. It doesn't announce itself. It's simply there.

My mother has made doenjangguk roughly ten thousand times in her life. The ratio she uses — two tablespoons of doenjang to two cups of anchovy stock — is the same ratio her mother used, which was probably the same ratio her mother used before that. There's no written recipe. It's calibrated through memory and taste.

Doenjang is aged fermented soybean paste, made from soybeans and salt through a months-long or years-long process that concentrates umami to an extraordinary degree. Two tablespoons of good doenjang dissolves into two cups of anchovy stock and immediately creates a broth that tastes as if it cooked for hours.

The vegetables are flexible. Zucchini and tofu are the most common combination — zucchini because it cooks quickly and absorbs flavor, soft tofu because it becomes almost silky in the warm broth. You can substitute mushrooms, potato, spinach, or any soft vegetable. The doenjang carries the flavor regardless.

The critical technique is dissolving the paste properly. Use the back of a spoon to press the doenjang through a small strainer into the hot stock, breaking up any lumps. Undissolved lumps of paste are too intense and unpleasant. A fully dissolved broth is smooth and even.

Doenjangguk takes fifteen minutes. In Korea, it's the soup that signals you are at home.
