In a medium saucepan, combine 1 cup of water and 3/4 cup of caster sugar over medium heat. Stir gently as the mixture warms, allowing it to come to a simmer for about 3–5 minutes until the sugar fully dissolves. Once the syrup is clear and glossy, remove it from the heat and let it cool for about 10 minutes.

In a large pitcher, pour in 2 cups of mango purée and add 1/2 cup of freshly squeezed lemon juice. Use a whisk to thoroughly blend the two, creating a vibrant, smooth mixture.

Slowly pour the cooled simple syrup into the pitcher with the mango and lemon mixture. Stir gently to combine everything well, allowing the sweet and tart flavors to meld together beautifully.

Gradually pour in 4 cups of chilled sparkling water, stirring continuously to incorporate the fizz into your Mango Lemonade.

You can either serve the Mango Lemonade immediately over ice for instant refreshment or cover and chill it in the refrigerator for 1 to 2 hours.

To elevate your presentation, serve your Mango Lemonade in clear glasses, garnished with fresh mint leaves or lemon slices.
