Citarella's small store at 1240 Sixth Avenue (bet. 50th and 49th streets) has recently started carrying bottles of freshly squeezed blood orange juice ($4.95 for a 1 quart bottle). The juice is delicious, not as sweet as orange juice, slightly tart and a deep scarlet red color. I have not seen any other stores that carry it. Just in case there are any other blood orange fans out there.
