No sweat! If your lemonade is too sweet, just toss in more water or lemon juice. When you pour it over ice, less sweet lemonade tends to thin out quicker. Also, remember, lemonade tastes way sweeter when it's warm compared to when it's ice-cold. So, before you go adding more water, give it a chill over some ice and see if it hits the spot. You might find it's just right!
