Grilled Pineapple With Maple Syrup Sauce

1 small pineapple
3 tbsp maple syrup
3/4 cup firmly packed dark brown sugar
2 tbsp fresh lime juice
1/2 tsp grated orange zest
1/3 cup fresh orange juice
2 tbsp finely chopped pecans

Leave the rind on the pineapple slices helps keep them intact on the grill and also conserves their juices. Spray the grids with cooking oil. Preheat the grill to a medium heat. Meanwhile, with a large sharp knife, trim off the top and bottom of the pineapple. Cut the pineapple crosswise into 8 rings (about 3/4 inch thick). With an apple core, sharp knife, cut the tough center core out of the pineapple rings. In a small skillet, combine the brown sugar, maple syrup, and lime juice. Brush the pineapple rings with 2 tablespoons of the brown sugar mixture and grill the pineapple, covered, turning occasionally, for 6 minutes or until golden brown. Meanwhile, add the orange zest and orange juice to the brown sugar mixture remaining in the skillet. Place the skillet directly on the grill or on the stove top over medium heat and bring to a boil. Cook until slightly thickened and syrupy, about 4 minutes. Place the pineapple rings on 4 plates, top with orange-maple sauce, sprinkle with the pecans, and serve. (You can prepare the whole desert in advance but don't sprinkle on the nuts until ready to serve.) Makes 4 servings.
