Ingredients

Lemon Simple Syrup:

6 lemons, washed—zested and juiced
2 cups water
3 cups sugar

Secret Ingredient Lemonade:

1 part lemon simple syrup
2 parts water
Raspberries or strawberries for garnish (optional)

Instructions

Zest all six lemons, then juice them. Use a fine-mesh strainer to remove seeds and pulp from the juice. Set the juice aside.
In a medium saucepan, combine the lemon zest, lemon juice, water, and sugar. Warm the mixture over medium to medium-low heat and stir frequently until the sugar dissolves and the mixture simmers gently for about 5–10 minutes. This extracts the essential oils from the zest and creates a flavorful lemon simple syrup.
Remove the pan from heat and strain the syrup through a fine-mesh strainer to remove the zest. Allow the syrup to cool to room temperature, then chill if desired.
To serve, mix 1 part lemon simple syrup with 2 parts cold water and stir well. Pour over ice and garnish with fresh raspberries or sliced strawberries if you like.

Tips and Variations

Adjust sweetness to taste: start with the 1:2 syrup-to-water ratio and add more water or syrup if you prefer a lighter or stronger lemon flavor.
For a brighter, more aromatic syrup, use a microplane to zest the lemons finely and avoid the bitter white pith.
Swap part of the sugar for honey or maple syrup for a different flavor profile; heat gently to dissolve.
To make an adult version, add a splash of white rum, vodka, or gin to each glass. A small amount goes a long way—start with 1 ounce per serving and adjust to taste.
Make ahead: store the cooled lemon simple syrup in a sealed container in the refrigerator.

Storage

Keep the lemon simple syrup refrigerated in a sealed container. It will stay fresh for several days—commonly 5–7 days—so you can mix fresh lemonade whenever you like without redoing the syrup each time.
