Pronounced "tea-in sin" Tien Tsin chili peppers are also known as Chinese Red Peppers or Tianjin pepper. You’ll also find them referenced as Tientsin as they are named after the province in China where they are native. These chilies are most popular when used in Asian cooking and especially in the Hunan or Szechwan styles. In this country we are most familiar with these as the bright red peppers in Kung Pao Chicken. If you have a recipe calling for Chinese Red Peppers these are the chilies they are calling for.
