Transfer to the refrigerator and let the fish meat paste rest for 15 minutes.
Prepare the Vegetables and Tofu
While salmon fish paste is resting in the refrigerator, prepare the vegetables.
Cut bitter gourd/melon at a diagonal into 12 ½ inch thick slices. Using a paring knife, carefully cut away the center with the seeds. Transfer to a bowl and sprinkle 1 teaspoon of salt over the prepared bitter gourd/melon. Allow it to sit for 30 minutes to draw out the bitter juices. Then, rinse and drain.
Cut each small eggplant into six ¾ inch thick slices with a slit in the middle. If you are using the long Chinese eggplant, cut the eggplant at a diagonal into twelve ¾ inch thick slices with a slit in the middle.
Cut a slit in each red chili and carefully remove the seeds inside. Wear a pair of gloves if necessary.
Cut the green peppers into quarters and carefully cut around each piece to remove the spongy core and seeds.
Peel the outer skin off the lotus root with a vegetable peeler. Cut into twelve ¼ inch thick slices. Boil the lotus root with ½ teaspoon salt for 3 minutes. Remove, rinse, and drain.
Remove tofu from packaging and transfer to a shallow bowl. Place several dishes on top of the tofu to press out the excess water. Drain and cut the block of tofu into quarters. Then, cut each quarter diagonal into 2 pieces. Using a teaspoon, carefully scoop out an indentation on the side where the piece of tofu was cut diagonally.
Cut fuchok (tofu skin) into 12 pieces of 7” x 3½” each. Wipe with a damp cloth to moisten and soften the fuchok.

Fill the red chili cavities with fish paste and smoothen the fish paste near the slit with your finger.
For the green pepper, fill the cavity with fish paste. Then, smoothen the top of the fish paste with your finger.
