Pu-pu platters are ubiquitous at Chinese-American restaurants and tiki bars, where they traditionally consist of bite-sized foods — like egg rolls, fried wontons, crab rangoon, skewered beef, fried shrimp — all arranged around a flame for reheating. The name comes from the Hawaiian word pū-pū, meaning shell or mollusk, but it’s been co-opted to refer to appetizers.
