I often include apples and grapes. The trick I learned from my mother for the apple not to turn brown, is that after peeling or slicing the apple she soak it in water with salt… mga 1 min will do. Promise hindi po magiiba kulay ng apples. :)
You can use oranges (can be used as petals), kiwi and strawberry.
You can try melons, mangoes and papaya.
Try to include oranges or cut bananas
