In a bowl, whisk all-purpose flour and salt.
Cut in cold butter until crumbly (with your hands or a pastry cutter).
Add ice water into the bowl one tablespoon at a time until dough comes together (7-8 is usually how many I need).
Form into a disk, pressing any loose pieces if needed and wrap tightly in plastic wrap. Chill for at 30 minutes.
About 20 minutes into chilling, preheat oven to 350F and start making filling.
In a mixing bowl, whisk corn syrup (light or golden), light brown sugar, eggs, melted butter, pure vanilla extracr, and salt until smooth. Then fold in pecans and set aside.
Roll dough on a lightly floured work surface to ⅛” thick and make rounds with a 4-inch cutter.
Press each round into a greased muffin tray, with a tart tamper if you have one.
Use a fork to poke a bunch of holes the bottom of the pie shells, then spoon pecan pie filling into each crust, about ⅔ full. Don’t overfill, they puff while baking. Optionally, place while pecans on top for a special touch.
Bake for about 23-25 minutes or until the tops are golden and the centers look just set.
Let them cool in the tray for 10 minutes, then gently twist to remove and cool completely on a wire rack.
