Pecan Pie Filling

Spread the pecan halves on a dry sheet pan in a single layer. Roast at 175 C (350 F) for 8–10 minutes, stirring once halfway through. You are not just toasting for color — you are driving off moisture so the nuts stay crisp through a long bake inside a wet custard.

In a large bowl, whisk together the dark corn syrup, brown sugar, melted (not hot) butter, salt, and vanilla until the sugar has partially dissolved and the mixture is uniform in color. The butter must be cooled to below 50 C or it will begin to cook the eggs when they are added. Rub a drop between your fingers — you should not feel undissolved sugar crystals, though some is acceptable at this stage.

Add the eggs one at a time, whisking each in fully before adding the next. Do not beat aggressively — you are incorporating eggs, not building foam. Excess air creates a soufflé-like filling that puffs and cracks dramatically in the oven. Whisk gently, just until each egg is fully absorbed and the mixture is homogeneous.

Arrange the toasted pecan halves in concentric circles in an unbaked 9-inch pie shell, flat side down, covering the entire bottom. Pour the filling batter gently over them — the pecans will float up and redistribute. Do not try to hold them in place; they will self-arrange as they bake. Fill to within 1 cm of the crust rim.

Bake at 175 C (350 F) on the lower-middle rack for 50–60 minutes. Shield the crust edge with foil or a pie shield after the first 20 minutes. The custard sets from the outside inward — the edges will firm up while the center still appears liquid. Do not overbake waiting for the center to set firm in the oven; it will finish cooking off-heat.
