Purple laver + Grass pea
Porphyra is a cold water seaweed that grows in cold shallow sea water. More specifically, it is a foliose red algal genus of laver, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea). There are considered to be 60 to 70 species of Porphyra worldwide and seven in the British Isles.

Lathyrus sativus, is a legume (family Fabaceae) commonly grown for human consumption and livestock feed in Asia and East Africa. It is a particularly important crop in areas that are prone to drought and famine, and is thought of as an 'insurance crop' as it produces reliable yields when all other crops fail.
Shared flavor compounds
These compounds appear in both Purple laver and Grass pea, giving them a molecular basis for flavor affinity, the pairing principle articulated by Francois Benzi and implemented in flavor-pairing research.
Why it works
The flavor-pairing hypothesis proposes that ingredients sharing significant aromatic compounds harmonize on the palate. Purple laver and Grass pea overlap on 20 key compound(s), which is why classic culinary traditions, and our deterministic matching algorithm, place them together.
