In a medium bowl, sift together the all-purpose flour, salt, baking powder, baking soda, and cinnamon. If you were using a stand mixer, remove the mixing bowl from the stand. Using a spatula, gently fold in 1/3 of the dry ingredients. Add 1/2 of the milk. Gently fold in the next 1/3 of the dry ingredients. Stir in the rest of the milk and end with the final 1/3 of dry ingredients. Fold until just combined. Add in the toasted and chopped pecans and gently fold until distributed through the batter.
