Recipes that use agave nectar instead of sugar?

For each cup of sugar called for in a recipe, substitute 2/3 cup agave and decrease other liquid by 1/4 cup.

e.g. if a recipe calls for 1/2 cup sugar, sub 1/3 cup agave and decrease other liquid by two tablespoons; if it calls for 2 cups sugar sub 1 1/3 cup agave and decrease other liquid by 1/2 cup.
