*To toast the pecans, preheat the oven to 350 degrees F. Spread 1-2 cups of whole pecans on a baking sheet in and even layer. Place in the oven and bake for 10-15 minutes, stirring halfway through cooking until toasted. Allow the nuts to cool completely and pulse in a food processor until finely ground. Use 3/4 cups of ground pecans for this recipe. *Alternately if you prefer to not make a lattice, you can simply lay the pie round over the filling, then, using a sharp knife, slice four holes in the top of the crust for air pockets. Proceed as directed above.
