Start by preparing a simple syrup because this step ensures the sugar blends seamlessly into the drink. In a small saucepan over medium heat, mix the water and sugar. Stir occasionally until the sugar is fully dissolved and the mixture turns clear. This should take around 4–5 minutes. Remove it from the heat and allow it to cool.
While the syrup cools, juice your lemons. Freshly squeezed lemon juice gives this lemonade a bright and zesty flavor, which pairs beautifully with the sweetness of the blue raspberry syrup. Strain the juice to remove any seeds or pulp, if needed.
Grab a pitcher and pour in the lemon juice and the cooled simple syrup. Add the cold water and blue raspberry syrup. Stir the mixture well to combine and watch the vibrant blue color swirl into the lemonade. Check the taste and adjust the sweetness or water as needed.
Now, fill the pitcher with ice to chill your lemonade instantly. Stir once more to ensure everything is well-mixed. If you want to elevate its look, garnish each glass with a sprig of fresh mint or a slice of lemon before serving.
Pour the lemonade into your favorite glasses, take a sip, and enjoy the perfect balance of tangy, sweet, and fruity flavors. This drink is best served fresh and cold!
