First, I whisk the eggs in a large bowl until smooth. Then I mix the sugar, cinnamon, salt, ginger, and cloves in a separate bowl to ensure the spices are evenly distributed. Next, I stir the pumpkin puree into the eggs until fully combined. Finally, I slowly add the evaporated milk and mix gently until the filling is creamy and uniform.
I pour the prepared filling into the unbaked pie crust and place it in a preheated oven. The pie bakes until the edges are set and the center has a slight jiggle. Once baked, I remove it from the oven and allow it to cool completely so the custard can firm up properly.
While the pie cools, I prepare the topping by melting brown sugar, cream, butter, and corn syrup in a saucepan over medium heat. I stir constantly until it thickens slightly. Then I remove it from the heat, mix in toasted pecans and vanilla, and let it cool before drizzling it over each slice.
