TIME FOR FREEZING
The time for freezing varies according to the quality of cream or milk or water; water ices require a longer time than ice creams. It is not well to freeze the mixtures too rapidly; they are apt to be coarse, not smooth, and if they are churned before the mixture is icy cold they will be greasy or "buttery."
The average time for freezing two quarts of cream should be ten minutes; it takes but a minute or two longer for larger quantities.
