It's a great time for a recipe isn't it? And this one is not only delicious and beautiful, but it's seasonal!
This is so wonderful, tangy, sweet and refreshing - you are going to love it!
2 Pomegranates, seeded
3-5 Ruby Red Grapefruits, peeled (depending on how much juice you want to make and the size of grapefruits - should yield about 2 or more cups of juice)
Put through a juicer and enjoy!
This is really a recipe for your juicer, but if you don't mind it on the pulpy side, you can certainly blend it up (and/or optionally strain it).
The important thing, though is you need to de-seed the pomegranates. You don't want any rind in there, as it will make the drink bitter. It seems more tedious than it actually is, but takes no more than a few minutes to do.

Here's another way which I haven't tried yet but looks even easier! http://www.metacafe.com/watch/448091/chefs_trick_deseeding_a_pomegranate_in_seconds/
