Morinaga's signature dish is undoubtedly their truffle somen with ikura.

Thin al dente wheat flour somen noodles are served cold in a truffle soy sauce dip and topped with spring onion and ikura. It is light, refreshing and slurp-worthy! Whilst the ikura and spring onion give this dish bursts of umami and herbaceous flavours, I recommend having it with some wasabi to give it an additional spicy kick.
