As substitutes for sugar for cooking purposes, corn sirup, molasses, glucose, maple sugar and sirup, and also honey come in for their share of usefulness. The question arises in the mind of many a housewife as to how much of these diluted sugars should be substituted in customary recipes. For this reason, the following facts may be of interest.
Corn sirup and maple sirup are not so sweet as sugar, and when used to replace it, should be increased from one half to two thirds. For instance, if a recipe calls for 1 cup of sugar, use as substitute 1 1/2 to 1 2/3 cups of sirup. In this case, allowance must be made for the increase in liquid. Every cup of sirup furnishes 1/4 cup of liquid; therefore for every cup of sirup that is substituted for sugar, reduce the original amount of liquid in the recipe 1/4 cup. Unless such allowance is made for the liquid that the sirup adds, an extra amount of flour is needed to obtain the necessary thickness to the batter, and a poor product is likely to result.
In using molasses and brown sugar, no change need be made so far as amounts for sweetening purposes are concerned, because what these lack in sweetness is largely made up in flavor. How-ever, the same allowance must be made for the liquid as when sirup is used. Glucose is best when used with part sugar, say sugar to 2/3 glucose by measure. When used thus, it is suitable for canning purposes, also for the making of sauces, etc.
Honey, one of the most staple sweetenings in the world, and probably the longest used, has not been in very common use for cooking purposes. Its sweetening power is about the same as that of sugar, and it should be used in the same proportion as white sugar, except that one fourth less of liquid should be used in a recipe with honey than with sugar. Honey is best adapted for table use; and for this purpose, it had better replace white sugar entirely.
