Can a "hot" ice cream mixture lose enough heat energy to ice to make ice cream freeze?
Actually, no. . This is because only plain water freezes at 0 degrees. If water contains any impurities, such as other liquids (maybe as a fruit or fizzy drink), dirt or salt, then this makes the water freeze at a lower temperature. [ This is because those impurities make the water less able to lose its heat energy, so it stays as a liquid for longer. Likewise, liquids such as cream or melted chocolate, which are typical ingredients in an ice cream mix, have freezing points much lower than 0 degrees. An ice cream mix may have a freezing point of about -3 degrees or less.
