It is a "bonito flour (powdered dashi)" that uses the blood of bonito and concentrates the attractive "nutritional value" of bonito. It is additive-free, salt-free, and rich in potassium, which has the effect of excreting salt from the body, so it is expected to have a salt-reducing effect, and is recommended for those who are concerned about salt and swelling. [Flavor condensed by ripening] Since the aged bonito flakes are further aged (re-ripened) to remove the peculiar peculiarity of blood, the bloody smell is removed, and the aroma, flavor, and umami are further condensed, making it a deep, rich and rich broth that stands out from other bonito stocks. 【Abundant heme iron】 Nutrients are concentrated in the blood joint, but it is especially rich in "heme iron", which has a high absorption rate into the body, so it is a product that I would like to recommend to women who are prone to iron deficiency, athletes, and growing children.　<Maternity Food Mark Acquired Products> [Rich even in small amounts] Since the flavor of tetsumaru is concentrated, put 10g (a little more than 1 tablespoon) in a dashi pack and add it to 500-600ml (about 3 cups) of water. You can get a thicker broth if you take it with cold brew. * How to use delicious tetsumaru twice in one time: No. 1 dashi can be used for miso soup and soup, and No. 2 dashi can be used deliciously for simmered dishes, tsukuni, and tossed dishes.
