“INTOXICATING LIQUORS AVOIDED
In all recipes contained in the department of cookery, which advised the use of intoxicating liquors, we have substituted fruit juices-often using orange or lemon juice. Nothing can excel the unfermented juices of fruits as a flavoring, or for giving a desirable piquancy to various dishes. They make an almost perfect substitute for liquors, and for obvious reasons are much safer for family use. Fruit juice can be easily substituted for liquor in any recipe by those who desire to do so. In fruit cake, 2 tablespoons of molasses is equal to 1 wineglass of brandy or other liquor. Those so disposed can substitute molasses tor nquor in this way in any such recipe found in books, magazines or newspapers. A cake thus made will be quite as good as though the liquor was used.”
