Tomato Sauce with Garlic and Orange

From the Mediterranean coast of Spain comes this distinctive sauce, whose flavors are reminiscent of bouillabaisse. Not surprisingly, it’s often served on grilled fish, but it is equally good on chicken and incredible over pork. If possible, use strong-tasting oranges—Valencias are a good choice—not overly sweet ones like navels. In Spain, the oranges used for this are very acidic, even bitter.
