When selecting green beans in the store, look for firm beans with a velvety texture and good color. A good bean will snap when broken in half. Avoid beans that are dull in color and have brown spots especially on the ends. Over mature beans will show the overgrown bean that is inside on the outside. Beans in this condition will be tough and most of the flavor will be lost.
