Borrowing from the local love of fried chicken, Leong came up with a variation of the preexisting dish. Instead of stir-frying the chicken, as is normally done, he deep-fried the chicken chunks. He then covered them with the typical sauce made from chicken stock, soy sauce and oyster sauce, and added the handful of cashews. He also included chopped green onions as a twist and it became an immediate hit with the local crowd. As word spread about the dish, so did the recipe. Leong's Tea House closed its doors in 1997, but Springfield-style cashew chicken is still being served at over 70 Chinese restaurants, as well as many non-Chinese restaurants, in and around the Springfield metropolitan area, and elsewhere in Missouri and other states. Springfield-style cashew chicken has been mentioned on The Food Channel, a nationwide syndicated radio program, and the floor of the U.S. House of Representatives.
