Hull the strawberries, removing the green tops.

Add the hulled strawberries to a blender along with 2 cups of water. Blend until smooth.

Using a fine mesh strainer or cheesecloth, strain the puree into a large pitcher.

Add the remaining 2 cups of water, sugar, and lime juice to the pitcher. Stir well until the sugar dissolves completely.

Taste and adjust sweetness or lime juice as desired.

Let the mixture chill in the refrigerator for at least 30 minutes.

Fill glasses with ice and pour the chilled agua fresca over.

Garnish with a slice of lime or a whole strawberry on the rim of the glass if desired.
