Tsukimi soba is a traditional noodle dish. It’s made by topping buckwheat soba noodles with an egg. The ingredients commonly include soba noodles, eggs, carrots, green onions, and a broth consisting of dashi, soy sauce, sake, and mirin. Once cooked, the noodles are placed into a bowl filled with the hot broth, and the dish is then topped with a raw egg and chopped green onions.
