After a lot of experimentation, we've come up with a juice that comes out pink, tastes incredible AND can help prevent breast cancer!
The general idea is to put the lemon in, then the tomato, then start feeding in watermelon until you hit 32oz.
Wash and stem the cherries. Place them in a blender or food processor and add about 1/4 cup water for every cup of cherries. Blend until the cherries are ground, but the pits are not completely. Pour the juice into a fine mesh colander or sieve to collect the pits and skins with a container underneath to catch the juice. Use a wooden spoon or spatula to press the juice through the sieve. Discard the pits.
