Adults who want a more palatable remedy against cough and sore throat can try mixing warm water with lemon and honey. No need to spit it out.
The sugar and fats in the mix interfere with the formation of ice crystals, and it takes a colder temperature to get the ice cream to really freeze. Therefore, we can't use straight ice to chill the ice cream base, because the ice will melt before the base gets cold enough. Salt provides the solution. Similar to sugar, salt affects how water freezes and effectively lowers the freezing/melting point of water. Creating a saltwater slush and packing this around our ice cream base allows us to cool the base enough so that it starts to thicken and freeze before the ice melts completely.
