Fusion cooking involves combining ingredients and cooking styles from different culinary traditions to create new dishes. It became popular in the 1970s when French chefs incorporated Asian cuisines into French dishes. There are several types of fusion cooking, including combining cuisines from different sub-regions within a country (sub-regional fusion), from different countries within a region (regional fusion), or between Asian and Western cuisines (continental fusion). Proponents argue that fusion cooking can increase health options and appreciation of global culinary traditions.
