Starfruit, like all citrus fruits, contains acids, so be careful to keep it of your eyes and away from open wounds. After you cut it, wash your hands with hot water and soap to prevent stinging in case you touch your eyes later. Display the starfruit however you see fit, depending on the occasion. All parts of the fruit are edible, so don't waste or throw away any scraps that you would rather eat. Wash your cutting board so that it will be clean and ready for future food preparations. Be sure the counter is clear of any fruit remains, as fruit can rot and smell over time. Starfruit can be used in a vast number of recipes, from starfruit chips to mango-orange sauce. Plan your recipe ahead of time so that you can be sure to account for all ingredients.
