When Martha made this cocktail at "Whiskey School" (aka: a class called "The Cocktails that made Whiskey Famous" at the Astor Center) she used the hugest, juiciest lemons ever...and the drink was way too tart! If this happens to you just add a little more simple syrup, to taste!  

Martha thought the drink tasted a bit like Fruity Pebbles. (She has a secret love of crappy sugar cereal!) Enjoy!
