Roll the fresh lemons on your countertop to maximize juice extraction. Then cut the lemons in half and juice them until you yield about 1 cup of fresh lemon juice.

In a large pitcher, combine the freshly squeezed lemon juice with the sweetened condensed milk. Stir vigorously until smooth and free of lumps.

Gradually pour in 2 cups of cold water while stirring continuously. Consider using ice-cold water for extra refreshment.

Taste your lemonade! If it needs more sweetness, add simple syrup to taste and stir well.

Chill the lemonade in the fridge for about 30 minutes or serve it immediately over ice.

Garnish each glass with fresh lemon slices and a sprig of mint leaves before serving.
