Kadyos or pigeon peas gives the broth a purplish color and enhances the taste of the soup. Lucky for us here in California, kadyos is available in most Filipino or some Asian grocery store. Check out the frozen area.
Frozen or dried kadyos takes longer boiling time. Soaking kadyos for few hours or overnight will lessen the boiling time.Start with 10 cups of water and add more if needed.
