* Agave nectar is a thick liquid sweetener. You will need to shake up the cocktail to really incorporate it into the drink (if not, it will sink to the bottom). I would recommend adding a bit, shaking, then tasting for sweetness. If the drink is still too tart, add some more nectar, shake and then taste again. For one of the drinks pictured above, I added 1 teaspoon of agave nectar.
