INGREDIENTS
Filling
- 1 1/2 lb Heirloom tomatoes cut into 1/4-inch slices
- 1 tsp Salt
- 1 1/2 cups Gruyère cheese grated
- 1/2 cup Chopped Herbs
- 2 tsp whole-grain mustard
METHOD
Tart Dough
1. In a large bowl, combine the flour and salt. Add the butter and blend into the flour using a pastry cutter until the butter is pea-sized. Add the water gradually and combine just until the dough sticks together when pressed. Form into a disc. Wrap in plastic wrap and refrigerate for 30 minutes.
2. With the rack in the middle position, preheat the oven to 400°F (200°C).
3. On a lightly floured surface, roll out the dough to inch (3 mm) thick. Line a 9-inch (23 cm) tart pan with the dough and prick the surface using a fork. Cover with aluminum foil and fill with pie weights.
4. Bake for 30 minutes or until the edge of the crust is lightly golden. Remove the aluminum foil and pie weights. Turn the oven down to 350°F (180°C).
Filling
5. Meanwhile, place the tomato slices on a rack over a baking sheet to allow the excess liquid to drain. Sprinkle with the salt and let drain for 15 minutes. Dry the surface of the tomato slices with paper towels.
6. Spread the mustard on the bottom of the tart. Layer the cheese, herbs and tomatoes on top.
7. Bake for 20 minutes or until the tomatoes are hot and the cheese is slightly melted. Let cool for 15 minutes before serving.
Avoid a soggy crust
Sweat the tomatoes with salt before cooking to release some water content. That’ll keep your crust from getting soggy.
