Remove the dirty grease from the pork backbone and soak it in cold water for half a day to drain the blood.

Slice potatoes, onions, and green onions into big chunks.

Boil your backbone once in boiling water and rinse it in running water.

Combine soybean paste in saucepan and add ginger, garlic and backbone.

Add red pepper powder, green onion, and chili pepper and boil it for 1-2 hours

When the backbone is cooked to a certain extent, add potatoes, onions, green onions, and cheongyang peppers and boil again Season with salt and pepper at the end. I couldn't put it in because I didn't have perilla leaves, so please add perilla leaves and perilla seed powder.
