Fava beans can be found fresh in grocery stores for a few weeks during the months of July and August only. They are also available frozen, peeled or unpeeled, in Middle Eastern grocery stores or sold canned. In you can’t find fava beans, you can replace them with fresh or frozen peas.
To prepare fresh fava beans, blanch them in a large pot of boiling water for about 1 minute to loosen their outer skin. Drain, then cool in a bowl of ice water. Then, remove their outer skins.
