• Use no more than 1 part sugar to 4 parts liquid. If there is too much sugar in the mixture, the ice will not freeze properly.
• Use ripe fruit. Don't be afraid to use what you might consider to be over-ripe fruit; the flavor is far superior to under-ripe fruit, which, when cold, is even more tasteless than at room temperature.
• Adding a few squirts of lemon or lime juice will help preserve the flavor.
• If you are adding alcohol, stir it in after freezing in the machine, and before the final freezing stage in the freezer.
