Instructions

  1. Prepare the noodles
    Soak the sweet potato glass noodles in cold water for at least 30 minutes. This helps soften them before stir-frying.

  2. Prep the vegetables

    • Julienne the carrot, red bell pepper, and onion.

    • Tear oyster and beech mushrooms into thin strips.

    • Cut spinach into bite-sized pieces (less than 2 inches).

  3. Cook the pork
    Heat a skillet with 1 Tbsp vegetable oil. Stir-fry the ground pork until about 80% cooked. Add minced garlic and continue cooking until fully done. Deglaze with cooking wine, then season lightly with salt and pepper.

  4. Stir-fry vegetables
    Add carrot and cook until about 70% done. Toss in red bell pepper and cook for 1 minute. Add mushrooms and stir-fry until tender. Then, add onion and cook 2 minutes. Finally, stir in spinach and cook for 2 minutes. Remove pork and vegetables from the skillet and set aside.

  5. Cook the noodles with sauce
    In the same skillet, combine soy sauce, dark soy sauce, oyster sauce, sugar, and remaining vegetable oil. Simmer for 2 minutes. Add soaked noodles and stir-fry for about 4 minutes, until glossy and tender.

  6. Combine everything
    Return pork and vegetables to the skillet. Stir-fry together for 3 minutes. Add oligodang syrup (or corn syrup) and toss well to coat.

  7. Finish & serve
    Drizzle sesame oil over the noodles and sprinkle with toasted sesame seeds. Serve warm and enjoy!
