Preheat oven to 350 degrees.
In a stove top pan, add sugar, dark Karo corn syrup, and salt. Mix together.
Simmer until sugar is completely dissolved, about 15-20 minutes. To test, dip a teaspoon in the mixture, let cool and taste.
Add butter and pure vanilla extract. Stir until incorporated.
Once done, removed from heat and let sit for about 10 minutes or until lukewarm. Then lightly beat the eggs and add them to the stove top pan.
Using a hand mixer, beat the eggs until incorporated.
Add pecans, mix together and pour into prepared pie shell.
Use a pie crust saver or place foil around crust to prevent crust from burning.
Bake for 50-75 minutes. Baking times may vary. Pie is done when it is not overly jiggly but semi-firm. If pie is still jiggly, continue baking checking every 5 minutes.
Remove, let cool, cut and serve!
This pie can be eaten warm (my personal favorite), room temperature or cold. Pick your favorite! Add whipped cream or vanilla ice cream.
