Cantonese spring rolls are deep-fried with a thin crispy wrapper and filled with minced pork, bean sprouts, and other vegetables. Not to be confused with the deep-fried cabbage-filled burritos known as “egg rolls” in Chinese-American restaurants.
In mainland China, where Spring rolls originated (in fried and non-fried incarnations), they are traditionally eaten during the Spring (Chinese New Year) Festival, hence the name.
