Triple Berry Tart

I found this recipe on the internet and the photos made my mouth water. Although we have a 9.5 inch tart pan, we also have an 11 inch model. Since I had enough fruit, I decided to do the math and increased the recipe for an 11 inch tart. That recipe follows the original 9.5 inch version.

I changed the cooking temperature for the recipes because my effort resulted in a charred tart.  It instructed that to cook the tart at 400 degrees F, which seemed awfully hot. It was. Next time I will use 350.

2 cups all purpose flour
3/4 cup finely chopped walnuts (use some sort of processor)
3/4 cup light brown sugar, lightly packed
12 tablespoons cold butter, diced
1 egg yolk
1 cup each of blueberries, blackberries, and raspberries
1 teaspoon sugar (optional) (seems pointless … the crust has so much sugar)

1. Preheat the oven to 400  350degrees F.
2. Combine the flour, walnuts, and sugar in a large bowl. Add the butter and the egg yolk. Mix, either by hand or with a mixer until crumbly. I felt like mine was too dry, but it turned out perfect, so don’t stress if it seems too “crumbly.”
3. Press 1 1/2 cups of the mixture into an even layer into the bottom of a 9 1/2 inch springform or tart pan.  Using a measuring cup works well to press the mixture into the sides/bottom.
4. In a separate bowl, combine the berries and lightly toss until evenly dispersed. Pour the berries on top of the crust, spreading evenly across the entire surface.
5. Sprinkle to remaining crumb mixture evenly over the berries. Bake for 40 to 50 minutes, or until lightly browned. Remove from the oven and cool for 10 minutes. Remove from the pan and serve warm or at room temperature.

11 inch version:

2-3/4 cups all purpose flour
1 cup finely chopped walnuts (use some sort of processor)
1 cup light brown sugar, lightly packed
16 tablespoons cold butter, diced
1 egg yolk
1 cup each of blueberries, blackberries, and raspberries
1 teaspoon sugar (optional) (seems pointless … the crust has so much sugar)

Note: I mistakenly used 12 T of butter instead of 16. Oops.
