Into your Cuisinart bowl add in the flour, salt and sugar. Pulse a couple of times until combined. Add in cold butter and egg yolk. Mix until crumbly. Through feed tube add in ice cold water until dough starts to come together. (If you don't have a cuisinart you can mix in a bowl)
Press the dough into the tart pan with your hands. Press into the crevices and up the sides. Refrigerate while you get filling ready.
Wash your pears and peel them (optional). Cut pears in half and then into slices. Squeeze 1/2 a lemon or orange juice over your sliced pears.Sprinkle the pears with cinnamon and gently mix Once pears are all sliced, take refrigerated tart pan out of fridge and layer them onto the dough in a pretty spiral. Next add the 2 Tablespoons of butter to the 1/2C- 3/4 C sugar, Flour and mix until light and fluffy. (I think a 1/2 C sugar would work great) Sprinkle over the top of all the pears.Drizzle 1-2 Tbsp of cream over the top of the tart Bake at 400 degrees for 35 min or until the top get golden in color and the crust is done.
