In a saucepan, bring water to a boil and add sugar, and remove from heat. Stir until it's melted and set in the refrigerator to cool.

In a blender (or a smoothie maker, if that's how you roll), blend the strawberries, ice and key lime juice until completely blended. Once the water and sugar is completely cooled, at it to the blended and blend thoroughly.

Garnish with fresh strawberries and a slice of key lime!
