I got some nice rhubarb at the farmers' market on Sunday and used some of it to make this juice. It has a really nice, revivifying tang. You can see from the above photo that I included some pineapple cores, but those aren't really essential to its success--I just had them around because there had been a bargain on organic pineapples, so I made a bunch of dried pineapple.
makes about 5 cups
20oz carrots, scrubbed and trimmed
2 fat rhubarb stalks
2 oranges, peeled
cores from 2 pineapple (optional)
Run through your juicer a couple of times, then chill.
