Squid

No part of the squid is wasted, from the flesh to the ink, and it is prized for its ability to be preserved in dishes such as shiokara (salted internal organs) and surume (dried squid). The white substance found on the surface of surume is in fact a type of amino acid called taurine. World-wide, while the Jewish religion forbids the consumption of seafood without scales such as octopus and squid, they are both popular in Mediterranean cooking.　It imparts the bitterness of histidine and hypoxanthine as well as sweetness. Thus it is preferable in cooked dishes rather than raw ones. Squid has a small amount of inosinate, a nucleotide.
