Low FODMAP Serving Size Info: Makes 1, 9-inch (23 cm) pie; 16 servings
For the Filling: Simultaneously on the other oven rack, toast pecans on a rimmed baking sheet until very lightly colored, about 5 minutes. Do not over brown. Cool on rack. Chop the nuts.
Whisk together the corn syrup, brown sugar, eggs, melted butter, vanilla and salt. Fold in chopped pecans and apples and pour into cooled crust.
Re-adjust rack to middle of oven. Bake pie for 10 minutes, then turn oven down to 350°F/180°C and continue to bake until the edges of the filling are set and slightly puffed; the center will be slightly wiggly, about 40 to 50 minutes. The center will firm up upon cooling. Cool on rack at least 2 hours before slicing. Pie may be made 1 day ahead. Store at room temperature lightly covered with foil. Serve warmed or at room temperature.
