In a large pot, combine beef or chicken broth, soy sauce, rice vinegar, sugar, sesame oil, minced garlic, and sliced ginger.
Bring to a boil, then reduce the heat and let it simmer for about 10 minutes.
Remove from heat and let it cool. Once cooled, strain out the ginger and garlic pieces.
Chill the broth in the refrigerator until cold.
Cook the naengmyeon noodles according to the package instructions. They typically require boiling for 3-4 minutes.
Once cooked, rinse the noodles under cold water to cool them down and remove excess starch. Drain well.
Divide the cold noodles into serving bowls.
Pour the chilled broth over the noodles.
Top with julienned cucumber, kimchi, julienned pear, and hard-boiled egg halves.
Sprinkle with sesame seeds and chopped green onions.
Add optional pickled vegetables or sliced radish if desired.
Enjoy your meal!
