A rare delicacy nationwide. Using only ayu eggs, the eggs are repeatedly fermented and aged for about a year. A hidden gem made more slowly than regular uruka, known to those in the know. Of course, it pairs well with drinks. In fact, we also recommend using it as a seasoning. These are bundles of umami. Just using a small amount can dramatically enhance the flavor of your dishes. Of course, it tastes great in sauce, but it's also delicious just by putting it on rice. Turning it into a rice ball as a salt substitute is also About Egg Uruka: For a while after production, we stir the product daily and let it rest in the warehouse to promote fermentation and make it delicious. Only those that have been thoroughly aged and have brought out their umami are shipped. *Color may vary depending on individual egg differences and aging period. There may be issues such as the color being different when purchased or the color darkening when left unused, but there are no issues. After opening, store in the refrigerator and serve promptly.
