[Traditional stone mill grinding method× condensing minerals from the Okinawan Sea] A special manufacturing method in which Okinawan seawater is slowly boiled down in a flat pot and carefully ground in a stone mill. It is rich in minerals such as calcium and magnesium, and has an ultra-fine particle finish that mellows and melts in taste. [Brings out the flavor of the ingredients to the maximum] It has many nigari ingredients and goes well with fish dishes and rice balls. Even a small amount of saltiness can be felt firmly, so the salt reduction is naturally achieved, and a pinch will greatly improve the quality of the dish. 【Ingredients/Ingredients】 Seawater (Okinawa Prefecture, Flat Pot) 【Contents】 1 bag×900g 【Shelf life】 2 years from the date of manufacture *If you purchase on this site, we will deliver products with a shelf life of 365 days or more. 【Microplastic countermeasures】 After passing raw seawater collected from the very beautiful coast of Okinawa through a 3 μm (micrometer) filter, it is then passed through a 1 μm to 2 μm filter several times to prevent microplastics. On top of that, we regularly test for microplastics and use safe raw materials that have undetectable test results.
