A spring roll is a hot snack or starter of mixed savoury ingredients, typically shredded pork, prawns, mushrooms, and vegetables, formed into a slightly flattened cylinder, wrapped in thin wheat dough, and deep-fried until crisp and golden. The name honours the Chinese spring festival, though the roll is now eaten year-round worldwide. The wrapper must be thin enough to shatter and the filling seasoned boldly with soy, ginger, and sesame; the contrast of crackling exterior and juicy interior is the whole pleasure. Served with sweet chilli or plum sauce, it is the archetypal Chinese takeaway starter. Fresh, unfried summer rolls are its delicate Vietnamese cousin.
