Jat-guksu
Jat-guksu is a Korean [noodle dish] consisting of wheat flour or buckwheat noodles in a bowl of cold broth made from ground pine nuts. It is a local specialty of Gapyeong, Gyeonggi Province, where a great deal of pine nuts are harvested in South Korea. The recipe is quite similar to another summer dish, kong-guksu, which is a noodle dish with a soy milk broth, but jat-guksu has a cleaner and more savory taste.
