Sherbets contain gelatin or whites of eggs and water-ice mixture.
Also for ice-cream or water-ice, when oranges are not to be had.
Sulfur dioxide or chlorine, for example, would not allow the formation of water-ice.
The precise moment when a water-ice becomes simple is when it is smoothly slipped into a long-stemmed sherbet glass.
A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere.
The water-ice was frozen in moulds, in the form of fruit, and suitably coloured.
