Toasting the pecans for 8 to 10 minutes before adding them deepens their flavor. Brown the butter slowly—once it smells nutty and the milk solids are amber, remove it from the heat immediately. Don't overbake the pie. The center should still have a slight wobble; it will continue to set as it cools. Let cool completely before slicing for clean, neat slices. This pie tastes even better the next day, making it perfect for preparing ahead. For extra flavor, sprinkle a pinch of flaky sea salt over each slice just before serving.
