Instructions
Pastry Pie Crust
Butter a tart pan that has a removable bottom.
Pulse flour, sugar, salt in food processor for a few seconds. Add butter.
Mix for about 30 seconds to one minute (it will look like coarse oatmeal).
Add egg yolk. Pulse for 20 seconds. Dump onto counter. Bring together, making sure all ingredients are incorporated. Press into tart pan. Freeze uncovered. Once frozen, wrap in foil.
To Bake: Bake at 375. Butter shiny side of foil. Place that side onto pastry. Bake frozen for 25 minutes. No need for pie weights.
Notes
I baked the plums and the pastry crust separately and then put it together and baked for ten more minutes. Bake plums in oven proof dish for 25 minutes. You could bake the plums in the tart shell at its frozen stage for about 40 to 50 minutes.
