In a small bowl, whisk together the flour, cinnamon and baking soda. Set aside.
In a large bowl, cream the butter and sugar with an electric mixer (hand held or otherwise). Once light and fluffy, beat in the egg yolk.
Gradually stir in the flour mixture. At some point a wooden spoon won't do so use your clean hands to mix until you get a soft dough.
Spray a 9x13 inch shallow baking pan with vegetable spray and start pre heating your oven to 325F.
Spread the cookie dough into the baking pan evenly and then brush the top with the egg white. Chop the pecan halves or grind in a nut grinder. Sprinkle them over the egg white brushed cookie dough,
Bake for 30 to 35 minutes until the edges just begin to brown a bit. Remove from the oven and let rest for about 10 minutes. Cut into 18 pieces but don't remove the cookies from the pan until they thoroughly cool.
I think I get my love for food and cooking from my mom, who was an amazing cook. She would start baking and freezing a month before Christmas in order to host our huge open house on Christmas afternoon. I watched and I learned...to this day I try not to procrastinate when it comes to entertaining.
My cooking style is pretty much all over the place, although I'm definitely partial to Greek and Italian cuisine. Oh yes, throw a little Cajun in there too!
