Begin by juicing fresh lemons until you have enough lemon juice to taste the zesty goodness, usually about 4-6 lemons. Measure out three cups of ice cubes and gather your choice of sweetener.

In a high-speed blender, combine the freshly squeezed lemon juice, three cups of ice, and your chosen sweetener. Blend on high for about 30-45 seconds until the mixture is a thick, slushy consistency.

Once you have the slushy base, add lemon zest and blend again for another 15-20 seconds until fully incorporated. Adjust sweetness as needed.

For a richer treat, incorporate optional ingredients like vanilla yogurt or ice cream, and blend on high for 20-30 seconds until creamy.

Pour your frozen lemonade into chilled glasses and garnish with fresh mint leaves or candied lemon peel. Serve immediately for the best experience.
