Just teasing but I really had never heard of 'pulses' used that way before your post. I usually count on a dictionary for translation:
The Very Best of British - The American's guide to speaking British
I was fortunate to live in King's Lynn (Norfolk) for a year in the late Nineties and frequently needed help. I also found that I needed a dictionary to translate British to British in some parts of the country.
I think pulses are legumes, called that in both countries. Can't think of yet another name for them.
By the way - welcome! I enjoy your posts.
