The fresh food of Iran is excellent and inexpensive. Produce must be disinfected to remove parasites. The pistachios are great, as are local potato chips. Fresh fish is brought in from the Caspian Sea and the Persian Gulf. Meat is restricted to beef and lamb.
Pork is forbidden.
Chickens are sold eviscerated and plucked. Dairy products are excellent, with eggs, pasteurized or sterilized milk, cream, ice cream, Iranian yogurt, and feta cheese, and a variety of foreign style cheeses available. It is difficult to get baking supplies because Iranians rely on professional bakers for everything. Household supplies such as plastic bags, aluminum foil, paper tissues, detergents, and cookware are available. There are no supplies for any kind of ethnic cooking, not even soy sauce.
