SC - Peas, Peas, Beautiful Peas...

[lilinah at earthlink.net]

In reading one of Scully's books on Medieval French cooking, he gives 
directions for a basic pea puree which is used in other recipes. He 
remarks that it was used in white dishes and the peas (dried, i'm 
guessing) were white.

I can't find white peas, although maybe i'm looking in all the wrong 
places - i can find dried green and dried yellow. But the only white 
things i'm finding are several kinds of white beans which are no 
doubt originally of New World origin.

Were those peas really white? If so, do white peas still exist? If 
so, where can i find some? And finally, if they exist, how are they 
different from "normal" green peas?

Thanks,
