To make ahead: Freeze ice cubes (Step 1) up to 1 week ahead. Refrigerate margarita mix (Step 2) for up to 2 days.
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, or for up to 1 week. Makes about 1 1/2 cups.
