Start by placing the sliced strawberries and chopped kiwis into a blender. Blend the mixture on high speed until it reaches a smooth consistency, approximately 30 seconds.
Pour the blended fruit mixture through a fine mesh sieve into a large pitcher. Use a spatula or the back of a spoon to press the juice through the sieve, effectively separating the juice from the pulp and seeds. Discard the remaining solids.
Into the pitcher containing the strained fruit juice, add the fresh lemon juice and your choice of honey or agave syrup. Stir the mixture vigorously until the sweetener is completely dissolved, ensuring an even distribution of flavor.
Gradually pour the cold water into the pitcher, mixing well to combine all ingredients. Taste the lemonade and adjust the sweetness if needed by incorporating additional honey or agave syrup, mixing thoroughly after each addition.
To optimize flavor and chill the beverage, refrigerate the lemonade for a minimum of 30 minutes before serving. This allows the flavors to meld beautifully.
To serve, fill glasses with ice cubes and pour the chilled strawberry kiwi lemonade over the ice. Garnish each glass with a sprig of fresh mint leaves for a refreshing aroma and vibrant presentation.
Notes
Adjust sweetness to taste and refrigerate for optimal flavor.
