these are some of my favorite cubes. not surprisingly, they are edible:
(not in order of preference)
those watermelons grown as cubes
it is also fun to cube things that do not typically come as cubes. you can cube melon (much better than the balls) and you can cube fruits and vegetables for kebabs. cubed steak is good and you can cube mango to make it easy to eat.
i guess the moral of this story is that cubed food is the only way to go right now. its more real than you could ever imagine.
j/k these are alfalfa cubes
