Afghanistan has a wide varying landscape allowing for many different crops. Afghan food is largely based upon the nation's chief crops: cereals like wheat, maize, barley and rice . Accompanying these staples are dairy products (yogurt, whey), various nuts, and native vegetables, and fresh and dried fruits; Afghanistan is well known for its grapes. Given their common history, Afghanistan, Iran, Tajikistan, Uzbekistan, and Pakistan (see Balochistan and North West Frontier Province) share similarities in cuisine.
