Tomato Tart

Directions

1. 1
   Combine flour and egg yolk in a bowl with a pinch of salt; quickly mix in butter with your hands, then add enough cold water to gather dough into a ball.
2. 2
   If time allows, refrigerate for 30 minutes or longer (you can leave it in refrigerator, well wrapped, for up to a day, or freeze for up to a month).
3. 3
   Heat oven to 450 degrees.
4. 4
   Use olive oil to lightly grease a 10- to 12-inch round pizza pan, preferably nonstick.
5. 5
   Roll out dough on a lightly floured surface or simply press it into pan, right up to edges.
6. 6
   Bake about 10 minutes, or until it is just beginning to color.
7. 7
   Remove and set on a rack.
8. 8
   Turn oven to 400 degrees.
9. 9
   Spread crust with mustard.
10. 10
    Core tomatoes; if they are very juicy, cut in half through equator and squeeze out some juice, shaking out most of seeds as well.
11. 11
    Cut into slices about 1/4-inch thick and place in a single layer on crust.
12. 12
    Sprinkle with salt, pepper and herbs, then drizzle with olive oil.
13. 13
    Bake tart about 30 minutes, or until tomatoes are shriveled and hot and crust is browned.
14. 14
    Serve hot or warm; this does not keep very well.
