Zipper cream peas are a popular variety. Some seed varieties appear to have no distinguishing eye color or body color other than that of white or pale, these seeds are said to have “no color”, and they are classified as “Creams”. The color of the seed itself determines the color of the broth when cooked. The darker the seed color the darker the broth. Seed with “no color”, white or pale, gives a clear broth. Zipper Cream Peas have a clear colored broth. The name Zipper came from the ease of unzipping the pea pod to expose the seed.
