Ume Kombu is a simple yet flavorful Japanese dish that combines the tangy taste of pickled plum (ume) with the savory richness of salted kombu. The addition of sesame oil enhances the dish, while fresh shiso leaves provide a refreshing, slightly bitter note that sharpens and balances the overall flavor. It's a dish that's both light and full of umami, perfect as a topping for rice or filling for onigiri.
