Cook 2 cups sugar with 1 cup water in a saucepan over medium heat until the sugar dissolves, about 5 minutes. Cool completely. For peach puree: Thaw a 16-ounce bag of frozen peaches, then puree in a blender with 1 teaspoon grated orange zest and 1/2 cup of the sugar syrup. Strain through a fine-mesh strainer and transfer to a bottle or jar. For strawberry or blueberry puree: Thaw a 16-ounce bag of frozen berries, then puree in a blender with 1/3 cup of the sugar syrup. Strain and store in a bottle or jar. Refrigerate purees until ready to use.
