Nothing beats the summer heat like this Chilly Berry Margarita. I once had one in Florida at an early dinner (~3:15pm) and received a brief respite from the sensation that I was being deep fried by the Florida sun. Florida isn't for Scandinavians, just sayin'...
Now this recipe makes two drinks, so don't be a stingy lush like me and try to keep them both because they melt. Also, strawberries contain a lot of pesticides so be sure to buy organic if you're feeling ridiculous.
Combine all ingredients (except garnishes) in a high-powered blender with 5 or so ice cubes.
Combine sugar, salt and lemon zest in a shallow dish. Dip the rim of a margarita glass into simple syrup, then sugar/salt/zest combination.
Pour blended drink into prepared glass.
