Place pineapple, ice, tequila, lime juice, Triple Sec and simple syrup in a blender. Puree until smooth.

Tip: To make your own simple syrup: Bring 1 cup sugar and 1 cup water to a boil in a medium saucepan, stirring frequently to dissolve the sugar. Let cool for 30 minutes and then refrigerate until cold, at least 1 hour. Makes about 1½ cups.
