I notice that recipes using Stevia list an amount of Stevia that is too small. Many of the authors have been using Stevia for a long time and thus don't need as much to satisfy their sweet tooth. Use 1 teaspoon Pure Stevia Extract Powder for each cup of Sugar and you should be fine. Pure means no fillers. Extract Powder is a fine white powder that should be 80-90%+ Stevioside and have a serving size of 28mg or less. Read the label before buying Stevia.
