" Marjan measured Bahar's unpredictable temperament according to the ancient and treasured Zoroastrian practice of gastronomic balancing, which pitted light and against dark, good against evil, hot against cold. Certain hot, or 'garm,' personalities tend to be quick to temper, exude more energy, and prompt all others around them to action. This energy often runs itself ragged, so to counter exhaustion, one must consume cold, or 'sard' foods, such as freshwater fish, yogurt, coriander, watermelon, and lentils. Most spices and meats should be avoided, for they only stoke the fires inside. (Tea, although hot in temperature, is quite a neutralizing element.) By contrast, for the person who suffers from too cold a temperament, marked by extreme bouts of melancholia and a general disinterest in the future, hot or 'garm' dishes are recommended. Foods such as veal, mung beans, cloves, and figs do well to raise spirits and excite ambitions.
To diagnose Bahar as a 'garmi' (on account of her extreme anxiety and hot temper) would have been simple enough, had she not also suffered from a lowness of spirit that often led to migraine headaches. Whether in a 'garm' or a 'sard' mood, Bahar could always depend on her older sister to guide her back to a relative calm. Marjan had for a long time kept a close eye on Bahar and knew exactly when to feed her sautéed fish with garlic and Seville oranges to settle her hot flashes, or when a good apple 'khoresh,' a stew made from tart apples, chicken, and split peas, would be a better choice to pull Bahar out of her doldrums.
