A staple of westernized Chinese cuisine and one of the favorite dishes of foreigners in China, kung pao chicken is a spicy stir-fry dish made with diced chicken, vegetables, peanuts, and Sichuan peppercorns. It was invented in the Sichuan province and has a unique, interesting origin story.
In the 19th century, a boy named Ding Baozhen fell into a river and almost drowned. A passing stranger saved him, and as the years went by, Ding grew up to become a government official. He went to visit the man who saved him and ate a dish made with diced chicken, peanuts, and spicy peppercorns while visiting his home.
Ding loved the dish so much that he asked the chef for a recipe, and then started serving it to his guests. The dish quickly spread in the Sichuan province, and many years later, it is still popular both in China and in the rest of the world. Although it's commonly eaten in North America, the dish is cooked differently and lacks the unique spice that makes the original so flavorful, because it was illegal to import it to the United States until 2005.
