Millionaire Pie

To make the crust:

1. Adjust an oven rack to middle position and preheat oven to 350 degrees. In a food processor, process cookies and pecans into fine crumbs. Add butter and process until combined. 
2. Using the bottom of a measuring cup, pack crumbs into the bottom and up the sides of a 9-inch pie pan. Refrigerate until firm, about 20 minutes.
3. Bake until lightly browned and fragrant, about 15 minutes. Cool to room temperature.

To make the pie filling:

1. In medium skillet over medium-high heat, cook drained pineapple, 1/4 cup sugar, and a pinch of salt, stirring occasionally until the pineapple is lightly browned and the liquid evaporates, about 15 minutes. 
2. In a food processor, process pineapple mixture until smooth, about one minute. Set aside. In medium bowl, whisk together the egg yolks, 1/4 cup sugar, and 1/4 teaspoon salt. Set aside.
3. In medium sauce pan, combine gelatin and 1/2 cup of pineapple juice concentrate. Allow to sit until the gelatin softens, about 5 minutes.  Cook over medium heat until the gelatin dissolves and the mixture is very hot but not boiling, about 2 minutes. 
4. Whisking vigorously, slowly add the gelatin mixture to the egg yolks. Return the yolk mixture to the saucepan and cook, stirring constantly, until slightly thickened, about 2 minutes. 
5. Remove from heat and stir in the remaining 1/2 cup pineapple juice concentrate and processed pineapple mixture. Pour mixture into a bowl and refrigerate until set, about 1 1/2 hours.
6. Meanwhile, in a stand mixer, whip heavy cream with remaining 1 tablespoon of sugar on medium-high speed to stiff peaks, about 3 minutes.
7. Working with 1 cup of whipped cream at a time, fold 2 cups whipped cream total into chilled pineapple mixture. Scrape mixture into cooled crust and smooth the top.
8. Top with remaining whipped cream. Refrigerate until set, at least 4 hours or overnight. Store leftovers in the refrigerator.
