Really excellent flavor! The flank steak was tender & cooked perfectly at 12 minutes total. The sweet & tangy orange/ginger balanced with the bitter radicchio was a beautiful combination. My only change next time would be to strain the orange rind before boiling down the marinade. A few bites were heavy with the orange peel & that flavor overpowered the rest. All in all an excellent response from my family. They've already requested it again. Thanks for sharing your creation, Tannic! Made, enjoyed & reviewed for Pick A Chef Fall 2008.
