I used to hate adding strawberries to a fruit salad (especially one with pineapple in it) because the red from the strawberries always seemed to bleed onto the other fruit. ... Until I discovered this easy trick! Wash your strawberries and put them to dry on a paper towel (while you prepare the other fruit). Then pat them dry and slice them ~ add to the fruit salad.
For some reason, wet strawberries bleed into the "wet" fruit salad ... but dry strawberries don't!! (or at least not as much)
