Mass-produced powder made from cocoa, sweeteners, and traces of lesser ingredients (possibly including lumps of sugar that pass for marshmallows) intended to be stirred into hot water to produce something that tastes something like hot chocolate, but isn't quite as good. Usually comes in envelopes, but also found in canisters. Depending on the brand, hot cocoa mix can sometimes be dumped into hot milk for better results. Swiss Miss is known for its hot cocoa mixes.
