Remove sponge-like parts and yellow leaves from the dalrae.

Soak dalrae in water with calcium powder for 5 minutes, then rinse thoroughly.

Drain the dalrae using a sieve and remove excess water.

Lightly tap the root part of the dalrae with a knife to enhance its spicy aroma.

Cut the dalrae into 4-5 cm pieces.

Wash the apple thoroughly and slice it thinly, keeping the skin on.

Remove the apple core and slice it into thin strips.

Mix the apple slices with 1 tbsp vinegar before combining with dalrae.

Prepare the seasoning: mix soy sauce, plum extract, chili powder, and sesame seeds.

Gently mix the seasoning with the dalrae and apple.

Optionally, add a small amount of sesame oil for extra flavor.
