Chinese food is among the most widely beloved cuisines in the U.S. Many dishes feature sweet and sour sauce made from a base of sugar and vinegar, which can add tangy, syrupy flavors to appetizers, entrees, and sides. Despite its popularity, not many people know about the origins and evolution of this tasty and satisfying sauce. Here's some interesting information about the creation of this Chinese food staple.


The earliest version of sweet and sour sauce likely originated in the Chinese provinces of Hunan and Guangdong. A popular theory states that similar sauces were developed in these regions independently around the same period. 

They featured sugar and vinegar combined with pineapples or pears, giving the concoction a pale yellow color and sweet fruity flavor. Chinese cooks often poured the sauce over fish, poultry, and vegetables or used it for dipping. 

Rise to Popularity

The sweet and sour sauce known and loved by Americans has roots in the United States. During a period known as the Chinese Exclusion that occurred during the late 19th century, Chinese laborers formed self-sufficient communities and prepared comfort foods that reminded them of home. 

They shared their cuisine with other non-Chinese laborers, who enjoyed the rich and savory flavors. This prompted restaurants in Chinatown districts to open and serve Chinese food to a more racially and economically diverse clientele.

By the early 20th century, Asian restaurants were serving large crowds. Due to the scarcity or expense of certain traditional spices, they experimented with new ways of adding flavor to dishes. Knowing Americans had a taste for sweet and acidic tomato-based sauces, they created sweet and sour sauce, which consisted of sugar, rice vinegar, pineapple, and a dash of ketchup or tomato paste, giving sweet and sour sauce its characteristic red hue. 

They began coating meat with the sauce and serving it alongside appetizers, and it became increasingly popular among customers. Toward the latter part of the 20th century, fast food restaurants started serving sweet and sour sauce for dipping chicken nuggets and fries, making this condiment even more popular. 

Common Dishes Prepared or Served With It 

Some of the most popular dishes served in modern Asian restaurants are sweet and sour pork, chicken, and shrimp. These entrees feature crispy-fried meats slathered in the delicious red glaze and served with white rice. 

Sweet and sour also remains a popular dipping sauce served with appetizers such as eggrolls, spring rolls, and crab rangoons. You might also use it as a condiment, drizzling it over fried rice, lo mein, or egg foo young for an extra burst of flavor.
