Begin by peeling, chopping, and boiling the yellow potatoes until they reach a tender consistency.

Transfer the boiled potatoes to a bowl, mash them finely, and then incorporate potato starch, salt, and room temperature water. Mix and knead until a firm, smooth dough ball is achieved.

Roll the dough into a lengthy log, then divide it into 16 pieces. Take each piece and roll it into chopstick-length strips.

Gently transfer the potato noodles into boiling water, allowing them to cook for approximately 5 minutes or until fully cooked.

Once cooked, place the noodles in cold water, drain them, and transfer them to a bowl.

In a separate bowl, craft the chili oil sauce by combining crushed red pepper, sesame seeds, dark soy sauce, Chinese black vinegar, sesame oil, fresh herbs, minced garlic, granulated sugar, Korean chili powder (Gochugaru), chopped green onions, and light soy sauce.

Arrange all toppings on the noodles in the bowl. Delicately pour the hot oil from the chili oil sauce over the toppings and noodles.

Ensure a thorough mix of noodles and toppings. Sprinkle sesame seeds over the Spicy Potato Noodles for a final touch of flavor.

Your Spicy Potato Noodles are now ready to be enjoyed! The unique combination of textures and flavors guarantees a delightful and satisfying culinary experience.
