Agave nectar, or a sweet liquid made from the nectar of the agave plant, has become increasingly popular as an alternative sweetener to table sugar. Agave nectar can be used in your home to cook with and bake with in your recipes with some modifications. As agave nectar is a liquid, is obviously will not act quite the same as table sugar in recipes, and it is a bit sweeter than table sugar. Less may be necessary to achieve the same amount of sweetness as sugar.
To convert a recipe from using regular sugar to agave nectar, you would use 2/3 cup of agave nectar for every cup of sugar the recipe calls for. Also, reduce other liquids in the recipe by 1/4 cup to 1/3 cup. If there are not any other liquids called for in the recipe, increase the flour by 1/4 cup to 1/3 cup to compensate for the additional liquid. Make sure that your agave nectar is at room temperature and that any butter in the recipe is softened before using in recipes. Also, reduce the oven temperature by 25 degrees as agave nectar can cause quicker browning. Lastly, if the recipe calls for creaming your butter and sugar, simply cream the butter and then mix in the nectar. After that, you can add in the eggs.
You may want to experiment with using agave nectar in your own recipes. It is not likely that all recipes will turn out exactly how they would with regular sugar, but you may be impressed with how well many will turn out.
