Add water and sugar to a pot. Heat over medium heat until sugar dissolves and turns slightly amber, about 15 minutes. Set aside for 5 seconds to cool slightly. Using a fork, flick the sugar in different directions over your greased mold (I used a small jam jar, but a bowl or cup would work). Allow to cool for 5-10 seconds to avoid burning your hands. Gently lift sugar from the mold and set aside. Repeat.
Drink
In a pitcher add berries, lime juice and tequila. Using a muddling tool or the back of a wooden spoon muddle the berries. Add juice and stir. Pour drinks over a glass filled with ice, garnish with spun sugar webs and serve.
