what is xo sauce
Developed in the 1980s in Hong Kong for Cantonese cuisine, XO sauce is made of roughly chopped dried seafoods, including scallops, dried fish and shrimp, and subsequently cooked with chili peppers, onions, and garlic.This dried seafood-based sauce bears similarity to the Fujianese Shacha sauce.n addition, the term XO is often used in the popular culture of Hong Kong to denote high quality, prestige and luxury. In fact, XO sauce has been marketed in the same manner as the French liquor, using packaging of similar colour schemes. In Hong Kong English, XO is pronounced exactly the same.
