How to consume

You can use fava bean as a fresh vegetable or as dry beans. Mostly dry beans have longer shelf life and you can use them in cooking. However, you may be able to enjoy the rich natural flavor only when you consume it as a fresh bean. You can soak fava bean in water to make it soft and then cook it. Remove the husk around the bean before cooking. You can consume it as a salad or by adding it to various dishes.


As any other Brassica group vegetable, fava bean also contains oxalic acid which has the potential to crystalize into oxalic stones in the urinary tract. Hence those diagnosed with kidney stones must avoid fava bean.
