Instead, try a natural sweetener called Stevia. In its liquid form, Stevia is 300 times sweeter than sugar. Another benefit of using Stevia is the fact that your blood sugar will not be raised by using it. A definite plus for anyone with diabetes.
There are other sweeteners available that could also be used, such as a raw honey, or agave syrup, or even barley malt syrup. Test them out and see which you prefer. And if all else fails, use a small amount of raw sugar. It is so much better than anything artificial.
