Start by peeling and dicing the mangoes. For the strawberries, hull them and slice into halves or quarters, depending on their size.

In a blender, combine the diced mangoes and sliced strawberries. Add about 2 cups of cold water and blend until smooth.

If you prefer a smoother texture, pour the blended mixture through a fine-mesh strainer into a large pitcher, using a spatula to push the juice through, leaving any pulp behind.

To your pitcher, add the freshly squeezed lemon juice, remaining 2 cups of cold water, and honey or sugar. Stir well until the sweetener is fully dissolved and the mixture is combined.

Give your lemonade a taste test and adjust the sweetness or tang as needed. If it's too tart, add more sweetener; if it's too sweet, add a splash of lemon juice.

Fill glasses with ice cubes, pour over the mango strawberry lemonade, and garnish with mint leaves if desired. Enjoy immediately!
