How to Make It
To prepare agrodolce, heat oil in a large nonstick skillet over medium-high heat. Add onion, shallots, and sugar to pan; sauté 12 minutes or until golden. Stir in wine, raisins, and vinegar; bring to a boil. Reduce heat, and simmer 9 minutes or until liquid almost evaporates. Remove from heat; stir in 1/4 teaspoon salt and 1/8 teaspoon pepper.
To prepare pork tenderloin, combine fennel seeds, 1/2 teaspoon salt, coriander, cumin, and 1/4 teaspoon pepper in a small bowl. Sprinkle pork with fennel seed mixture. Place pork on grill rack coated with cooking spray; grill for 20 minutes or until a thermometer registers 155° (slightly pink), turning pork occasionally. Let stand for 10 minutes. Cut into 1/4-inch-thick slices. Serve with agrodolce.
