Prepare toppings:Boil an egg for about 8 minutes for the topping. Halve it.Slice the green onion into thin rounds (about 2~3 mm). Julienne the onion and cucumber into thin strips for topping. If you like it spicy, slice a hot pepper at this stage as well.
Snip the topping kimchi into small pieces with scissors, no cutting board needed, which makes cleanup easy.
Add 3 cups of water to a pot. Once boiling, cook the noodles along with the vegetable flakes from the packet. Cook for the time listed on the package.
Then rinse under cold water for a chewy texture.
Make the cold ramyeon broth: mix 1 ramyeon seasoning packet, sugar, soy sauce, and vinegar together, then microwave for 20 seconds twice. Add cold water, stir well, and drop in ice to chill it down.
Top with cucumber, onion, kimchi, and boiled egg, then finish with green onion and sesame seeds. If you prefer extra heat, slice a spicy pepper and add it instead of green onion.
