What is labelled Bok Choy may come in 2 forms: traditional true bok choy () or Shanghai bok choy (). Regular bok choy is usually more expensive and has a dark crinkly colored leaves and stem portions that are white and crisp texture that is more suitable to Cantonese style cooking, stir fries, and simple or raw preparations. Shanghai bok choy has greater availability in most American Markets and has mild tasting spoon shaped leaves that are lighter green with stems that are jade green instead of white. The texture of Shanghai bok choy is less crisp and gets slimy if overcooked but otherwise can be substituted in many cooking applications when true bok choy is unavailable.
