Purple Hull Peas

A bowl of Purple Hull pea soup is a popular Southern comfort food. Purple Hull peas are often confused with black-eyed peas. Here is how these two are different: although both come from the cowpea family, they are not identical crops. The color is the first clue – when you open the pods to reveal the seeds, the cream-colored Purple Hull peas have pink-colored eyes, which is why it is also called Pink-Eyed Peas. A black-eyed pea, as the name suggests, has a black or dark brown eye.

The pod (or the hull) of the purple hull peas are slender and elongated, with a length ranging from 7 to 15 centimeters and each one containing 6 to 13 seeds. The seeds are oblong and kidney-shaped. You can tell what stage of maturity the pod or hull is based on the color. It starts from light green and then the color changes to purple-green, light purple, and deep burgundy as it reaches maturity. Color is not the only thing that changes as the hull matures, so does the texture. It starts tender and crisp and will eventually become dry, fibrous, chewy, and tough. The seeds inside the hull develop a glossy sheen. It is common to see cream-colored seeds but there are also ivory-green seeds although both have the same distinctive purple or pink eye that distinguishes them from the black-eyed peas.
