Dorie's Lemon Tart with Blueberry Topping

If you didn't already know that Dorie Greenspan is the queen of all baking, consider yourself told. :) This woman just keeps knocking recipes out of the ballpark. And her tarts? Oh... my... word! When I hosted for TWD back in May, I chose the Classic Berry Tart and fell in love. It is probably one of my favorite Dorie recipes of all time. Enter this amazing lemon tart (TWD made this before I joined the group) and I am now confused because it is so incredibly delicious!

The lemon filling is so creamy and so lemony and so good. This tart was fantastic plain but I couldn't resist adding some blueberries to a few slices. Lemons and blueberries are a match made in heaven.

I really hope you'll give this tart a try because you won't be disappointed!

The Most Extraordinary French Lemon Cream Tart
Dorie Greenspan

1 9-inch tart shell, fully baked and cooled (recipe below)

1 cup sugar
finely grated zest of 3 lemons
4 large eggs
1/2 cup freshly squeezed lemon juice (from 4 to 5 lemons)
2 sticks plus 5 tablespoons unsalted butter, at room temperature and cut into tablespoon-sized pieces

Getting Ready: Have an instant-read thermometer, a strainer and a blender (first choice) or food processor at hand. Bring a few inches of water to a simmer in a saucepan.

Put the sugar and zest in a large heatproof bowl that can be set over the pan of simmering water. Off the heat, rub the sugar and zest together between your fingers until the sugar is moist, grainy and very aromatic. Whisk in the eggs, followed by the lemon juice.

Set the bowl over the pan, and start stirring with the whisk as soon as the mixture feels tepid to the touch. Cook the lemon cream until it reaches 180 degrees F. As you whisk—you must whisk constantly to keep the eggs from scrambling—you’ll see that the cream will start out light and foamy, then the bubbles will get bigger, and then, as it gets closer to 180 degrees F, it will start to thicken and the whisk will leave tracks. Heads up at this point—the tracks mean the cream is almost ready. Don’t stop whisking or checking the temperature, and have patience—depending on how much heat you’re giving the cream, getting to temp can take as long as 10 minutes.

As soon as it reaches 180 degrees F, remove the cream from the heat and strain it into the container of the blender (or food processor); discard the zest. Let the cream stand, stirring occasionally, until it cools to 140 degrees F, about 10 minutes.

Turn the blender to high (or turn on the processor) and, with the machine going, add the butter about 5 pieces at a time. Scrape down the sides of the container as needed as you incorporate the butter. Once the butter is in, keep the machine going—to get the perfect light, airy texture of lemon-cream dreams, you must continue to blend the cream for another 3 minutes. If your machine protests and gets a bit too hot, work in 1-minute intervals, giving the machine a little rest between beats.

Pour the cream into a container, press a piece of plastic wrap against the surface to create an airtight seal and refrigerate for at least 4 hours or overnight. (The cream will keep in the fridge for 4 days and, or tightly sealed, in the freezer for up to 2 months; thaw it overnight in the refrigerator.)

When you are ready to assemble the tart, just whisk the cream to loosen it and spoon it into the tart shell. Serve the tart, or refrigerate until needed.

Sweet Tart Dough

1-1/2 cups all-purpose flour
1/2 cup confectioners’ sugar
1/4 teaspoon salt
1 stick plus 1 tablespoon (9 tablespoons)
very cold (or frozen) unsalted butter, cut into small pieces
1 large egg yolk

Put the flour, confectioners’ sugar and salt in a food processor and pulse a couple of times to combine. Scatter the pieces of butter over the dry ingredients and pulse until the butter is coarsely cut in—you should have some pieces the size of oatmeal flakes and some the size of peas. Stir the yolk, just to break it up, and add it a little at a time, pulsing after each addition. When the egg is in, process in long pulses—about 10 seconds each—until the dough, which will look granular soon after the egg is added, forms clumps and curds. Just before you reach this stage, the sound of the machine working the dough will change—heads up. Turn the dough out onto a work surface and, very lightly and sparingly, knead the dough just to incorporate any dry ingredients that might have escaped mixing.

To press the dough into the pan: Butter a 9-inch fluted tart pan with a removable bottom. Press the dough evenly over the bottom and up the sides of the pan, using all but one little piece of dough, which you should save in the refrigerator to patch any cracks after the crust is baked. Don’t be too heavy-handed—press the crust in so that the edges of the pieces cling to one another, but not so hard that the crust loses its crumbly texture. Freeze the crust for at least 30 minutes, preferably longer, before baking.

To bake the crust: Center a rack in the oven and preheat the oven to 375 degrees F.

Butter the shiny side of a piece of aluminum foil and fit the foil, buttered side down, tightly against the crust. (Since you froze the crust, you can bake it without weights.) Put the tart pan on a baking sheet and bake the crust for 25 minutes. Carefully remove the foil. If the crust has puffed, press it down gently with the back of a spoon. For a partially baked crust, patch the crust if necessary, then transfer the crust to a cooling rack (keep it in its pan).

To fully bake the crust: Bake for another 8 minutes or so, or until it is firm and golden brown. (I dislike lightly baked crusts, so I often keep the crust in the oven just a little longer. If you do that, just make sure to keep a close eye on the crust’s progress—it can go from golden to way too dark in a flash.) Transfer the tart pan to a rack and cool the crust to room temperature before filling.

Blueberry Topping

1 cup fresh blueberries, divided
1/4 cup sugar
2 TBSP water
1 tsp lemon juice

Combine 1/2 cup blueberries, sugar, and water in saucepan. Bring to a boil; reduce heat and simmer until berries pop. Remove from heat and strain out syrup; stir in lemon juice (discard cooked berries). Pour syrup over remaining 1/2 cup berries. Serve over tart.

I also LOVED this tart- it was picked before I joined TWD too but I made it for my mom on Mother's Day because she is a lemon fanatic. The texture was so amazing! After seeing your pictures now I want to make it again this week!
