Raw fava beans (broad beans) are not toxic. However, they are easier to digest if you cook or fry them. It is important to cook broad beans on medium and not high heat so that the beans don’t split. Whole broad beans can be stored in the refrigerator longer than shelled beans.
From Wikipedia: “Vicia faba, also known as the broad bean, fava bean, faba bean, field bean, bell bean, or tic bean, is a species of flowering plant in the pea and bean family Fabaceae. It is native to North Africa southwest and south Asia, and extensively cultivated elsewhere. A variety Vicia faba var. equina Pers. – horse bean has been previously recognized.”
“Broad beans are generally eaten while still young and tender, enabling harvesting to begin as early as the middle of spring for plants started under glass or overwintered in a protected location, but even the main crop sown in early spring will be ready from mid to late summer. Horse beans, left to mature fully, are usually harvested in the late autumn, and are then eaten as a pulse. The immature pods are also cooked and eaten, and the young leaves of the plant can also be eaten, either raw or cooked as a pot herb (like spinach).
Preparing broad beans involves first removing the beans from their pods, then steaming or boiling the beans, either whole or after parboiling them to loosen their exterior coating, which is then removed.
The beans can be fried, causing the skin to split open, and then salted and/or spiced to produce a savory, crunchy snack. ...
Dried and salted fava beans are a popular snack in many Latin countries.
Broad beans are widely cultivated in the Kech and Panjgur districts of Balochistan Province in Pakistan, and in the eastern province of Iran. They are called bakalaink in the Balochi language, and baghalee in Persian.”
