This recipe is related to this Octopus carpaccio (Recipe ID: 590632). I mixed chilled capellini with Genovese sauce.
I tried a chilled pasta dish at a family restaurant before and I liked it. I tried to recreate a similar dish from memory. Since then, I make this pasta every summer.
Adjust the seasoning according to the saltiness of the Genovese sauce, cooking liquid, tuna, and octopus.
Enjoy Japanese food around the world.
