Have you tried to eat young peas just picked from the plant? Eat them raw. They are tender, extremely sweet and addictive. The taste of freshly picked peas does not have anything to do with that of peas bought in the shop, probably picked more than 20 hours before, and even less with the flavor of frozen peas.
Young peas cooked as soon as they are picked are also a completely different experience. Petit pois, with their tiny seeds, come close to this experience or the mange tout and sugar snap varieties, where the pods are so tender that you don’t need to shell the peas, just steam and eat them with a little butter.
