Place sugar in a large nonstick skillet over medium heat, and cook until sugar dissolves (do not stir). Add walnuts, stirring until coated, and remove from heat. Spread walnuts in a single layer on wax paper, and let stand at room temperature until dry.

Remove scallops from pan, and set aside. Add remaining orange juice mixture to pan. Bring to a boil, and cook 2 minutes. Return scallops to pan. Divide scallops and sauce evenly among 4 plates. Sprinkle each serving with walnuts. Serve with Spiced Carrots.
Have made many times since it was printed. Quick & easy. Only things we've changed over the years is now we steam the carrots & use a ricer instead of mashing. Usually serve with simple steamed green veg like broccoli. Excellent.
