Snow  Peas are peas that are eaten for the sweet pods. They originated in Asia, and are the familiar ingredient in many Chinese stir fries.The seeds do not develop as an English pea does. They are deep green and flat with a tiny string on the seed side of the pod or legume. 

These are an early maturing legume. They have a natural sweet flavor. The pods should be tender and green with no yellow showing through, as this denotes over ripeness. The pods should crackle when open. Buy for immediate use as they loose their sugar and sweetness the longer away from harvest time.

Snow Peas are high in vitamins A and C, are loaded with fiber, and a 4 oz. serving is 60 calories. 

Avoid flat, dry and mottled looking pods. Peas are one of the earliest of the summer harvest vegetables. They are graded U.S.#1 and U.S. Fancy. 

Snow Peas should be stored at 33 to 38 degrees F. One pound of peas will serve 4 persons. 

Pack size: bushel 30/35 lbs. net=35-40# gross.
