sundubu jjigae is a simple spicy stew made with soft uncoagulated tofu. This tofu is produced without being pressed fully to remove the water, thus forming the block that is known as soft tofu. The dish is made with freshly curdled extra soft tofu (sundubu) which has not been strained and pressed, vegetables, sometimes mushrooms, onion, optional seafood (commonly oysters, mussels, clams and shrimp), optional meat (commonly beef or pork).
