Mix flour and 1 tsp nutmeg together.

Mix 1 TBLSP sugar and ¼ tsp nutmeg together in small bowl and set aside.

Cut cold butter into small pieces and mix into flour mixture until it resembles coarse sand.

Stir ⅓ c. sugar into flour mixture.

Stir in one egg yolk with fork.

Then use hands to knead it together for several minutes until dough forms a ball.

Press flat into greased 9 inch pie plate or 8 inch square glass pan.

Mark slices carefully (not going very deep at all) with a sharp knife.

Poke fork holes half an inch apart all over the dough surface.

Sprinkle the extra nutmeg/ sugar mixture over the top.

Bake at 325 degrees for about 35 minutes. Watch carefully. Let it brown just a bit on the edges, being careful not to overcook (or undercook). It should be golden underneath (you can look through the clear pie plate) but if the golden gets too dark it will taste burnt.

Cut the slices in the pan, but then let it cool completely before getting them out or it will crumble apart.
