On Mexico’s northwest border, especially in Mexicali, spring rolls are known as chunkun.
Chunkun is a regional name used near the United States–Mexico border, particularly in Mexicali, Baja California. The rolls are generally deep-fried and served with ketchup, sometimes finished with a dot of hot mustard for dipping or decoration.
The term is unusual because it is not the standard name throughout Mexico. In many other Mexican settings, spring rolls are simply called rollos primavera. The regional word may be related to the Korean term chungwon, although that connection is presented as a possibility rather than a firmly established derivation.
This is a useful example of how immigrant cuisines develop local vocabularies. Similar Chinese-style rolls have distinct names elsewhere in Latin America, including arrollado primavera in Chile and Taco Chino in Costa Rica.
