I remember a very long thread on Chowhound which detailed the many food related differences between British, American and, to a lesser degree, Australian English. You’re right, Madrid, on all your calls here. We also have sugar snap peas, as well as the mangetout.
By the by, my partner worked as part of a Europe-wide procurement team for an oil company. The various managers used to hold meetings in its various regional centres, including Copenhagen. On the table was a bowl of peas, still in the pods, intended as a snack. The Skandis were surprised/amused when she started to pod a couple, as their custom is to eat the pod as well.
