Snap pea

Snap peas (Pisum sativum var. macrocarpon), also known as sugar snap peas, are a cultivar group of edible-podded peas that differ from snow peas in that their pods are round as opposed to flat. The name mangetout (French for "eat all") can apply both to snap peas and snow peas. Commonly thought to be from China, snow peas originated in the Mediterranean, and were grown widely in England and Europe in the nineteenth century. The Chinese adopted these peas into their own cuisine from the English, and they have been known as Chinese snow peas ever since.
