Gamjasaelleodeu is a traditional potato salad originating from South Korea. Although there are many variations, the salad is usually made with a combination of potatoes, carrots, cucumbers, onions, hard-boiled eggs, Fuji apples, mayonnaise (Kewpie is preferred), salt, and black pepper.

The potatoes and carrots are cut into cubes and boiled until fully cooked. The cucumbers and onions are diced and sprinkled with salt. The potatoes are gently mashed and mixed with the carrots, cucumbers, onions, eggs, apple chunks, and mayonnaise.

The salad is seasoned with salt and pepper to taste before serving. It's usually served as a side dish at Korean BBQ restaurants and goes really well with bulgogi and galbi.
