Caipiroska

Fill an 8-ounce highball glass with the ice and set aside.

Pour the lime juice, vodka, and simple syrup into a cocktail shaker. Squeeze the juice from the lime quarters into the shaker and add the squeezed rinds to the shaker, too. Add the ice from the glass and shake for at least 30 seconds (it’s longer than you think!). Pour the entire contents of the shaker (including the ice and lime rinds) into the glass and serve ice cold.
