A few years ago, we got our hands on the recipe for the red sangria from Rita's Kitchen, but try as we might, we just can't perfect the blend served at the casual restaurant at the Camelback Inn. Red wine, orange juice, vanilla, sugar, cut-up fruit, and — what? We suspect we weren't told the whole truth. But we can't blame Rita's. Some secrets are too good to give away. And we're more than happy to sit on the patio here — under the bubble lights, with live music playing and fires roaring in the winter — and contemplate just what might be in that sangria. Nutmeg? Cinnamon? We'd better order one more. You know, for experimental purposes only.
