Peel and cut the potatoes into halves or thick slices. Trim the edges to prevent breaking during cooking.

Slice the green chilies and green onion diagonally.

Soak the potatoes in cold water to remove excess starch while preparing the seasoning.

Mix all seasoning ingredients except sesame oil and sesame seeds in a bowl.

Drain the potatoes and stir-fry them in a pan with oil until their surface becomes translucent.

Add 1 cup of water or anchovy stock to the pan and bring to a boil.

Reduce heat to low, add the seasoning mixture, and simmer until the potatoes are tender and the sauce thickens.

Add sliced green chilies and green onion, stir briefly, and turn off the heat.
