Peel the potatoes.Cut them into medium bite-sized (about 3-4 cm).Rinse briefly in cold water to remove excess starch.Drain well so they don’t splatter when stir-frying. Shishito Peppers
Rinse under running water. Pat dry.Remove the stems (optional, but recommended).Keep them whole if they are small enough; if the size is too big, cut into half but cook less than whole peppers. It might become too soft. If you poke small holes in the shishito peppers using a toothpick or fork, the seasoning will soak in better and the dish will become even more flavourful. Onion
Peel and slice into thin strips.Not too thin, just enough to soften slightly while cooking. Kelp stockPut a piece of kelp in cold water(1cup), heat it gently until just before boiling, then remove the kelp Heat a pan with a little oil. Add the diced potatoes and stir-fry for 2–3 minutes until the surface is lightly coated. This helps keep the potatoes from breaking apart and adds extra flavour.
Add sliced onions and stir-fry for about 1 minute.
Add all the seasoning ingredients (soy sauce, cooking wine, sugar, corn syrup, minced garlic, etc.)

Pour in 1 cup of kelp broth.
Reduce to medium heat and simmer for 8–10 minutes, until the potatoes are about halfway cooked.
Add the shishito peppers and continue simmering for about 3–4 minutes, just until the seasoning gets absorbed. Don’t overcook them—they taste better with a bit of crunch.
Turn off the heat and drizzle a little sesame oil over the dish.
Sprinkle sesame seeds on top, if you like.
