Khoresh Seeb is a highly adaptable stew whose stars are the firm and tart apples (Seeb in Farsi) that are gently sauteed in butter or ghee and then placed on top of the stew as it finishes cooking.
The base of this dish is made with beef and yellow split peas, patiently cooked in a turmeric and tomato sauce which by itself is often called Gheymeh. Gheymeh is not only served alongside fried or roasted potatoes, but is also used as a decorative topping on various dishes such as Aash.
Persian cucumbers have ruined it for me! When you grow up eating cucumbers in the way that Americans eat apples and oranges, you are in for a disappointment the first time you cross paths with an ordinary cucumber. Persian cucumbers are delicate, high on cucumber flavor, and low on the chalky/bitterness factor. Their skins are sweet and soft, though frequently peeled and sprinkled with salt and pepper, allowing the cucumber to be eaten as you would eat a banana.
