Harvesting Broad Beans (Fava)
When ready: Pods are plump, 15-20cm long, and beans inside are visible as bumps. For fresh eating, harvest when beans inside are bright green and about thumb-nail sized. For drying, leave pods on plant until completely brown and dry.
How to harvest: Snap or cut pods from stem. Start harvesting from the bottom of the plant (earliest pods). For fresh eating, pick regularly to encourage continued production. Inner skin of individual beans can be removed after blanching for best texture.
