About this dish

Kongip-doenjang-muchim dresses boiled soybean leaves in doenjang and perilla oil - a rustic Korean banchan more commonly found on countryside tables in Jeolla and Gyeongsang provinces than in urban kitchens.

Soybean leaves are larger and thicker than perilla leaves, with a chewy, almost fabric-like texture after cooking. Fresh leaves are a seasonal ingredient available only in summer, typically sourced at rural markets or directly from farms rather than supermarkets. Boiling for five to six minutes softens the tough fibers while preserving the earthy, beany aroma unique to the leaf. Since doenjang is the primary seasoning and can easily over-salt the dish, diluting it with a tablespoon of water brings the intensity to the right level. Perilla oil is chosen over sesame oil because its grassy, nutty profile harmonizes with the leaf's herbaceous character. Gentle hand-mixing is essential - aggressive tossing tears the softened leaves.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps

1

Prep

Trim any tough stem ends from 260 g soybean leaves, then rinse the leaves several times under running water.

Open the thick leaves as you wash so soil or grit does not stay trapped between folded layers.
2

Control

Bring a large pot of water to a strong boil and add a small pinch of salt.

Add the soybean leaves and boil over medium-high heat for 5 to 6 minutes, until the leaves darken and the stems bend easily.
3

Heat

Lift one leaf and check the fibers.

If it still feels stiff or leathery, boil 1 to 2 minutes longer, but stop once it folds softly so the earthy leaf aroma does not wash out.
4

Heat

Rinse the boiled leaves immediately in cold water to stop residual cooking.

Squeeze out moisture firmly with both hands, then cut into 3 to 4 cm pieces so the dressing can cling to the cut surfaces.
5

Season

In a bowl, loosen 1.5 tbsp doenjang with 1 tbsp water first.

Mix in minced garlic, green onion, perilla oil, red pepper flakes, and ground sesame until the paste is even and no salty clumps remain.
6

Finish

Add the dressing to the leaves in portions and mix lightly with your fingertips, folding instead of crushing so the softened leaves do not tear. Rest for 10 minutes, taste for seasoning, then plate and serve.

Key technique: Earthy soybean leaves are boiled and dressed in rich doenjang and nutty perilla oil.
Finish cue: Add the dressing to the leaves in portions and mix lightly with your fingertips, folding instead of crushing so the softened leaves do not tear.
Avoid this: If leaves are tough, extend boiling by 1 to 2 minutes.
