The Most Extraordinary French Lemon Cream Tart

From Baking: From My Home To Yours by Dorie Greenspans 

Note: For this recipe you will need a candy thermometer and a blender or food processor.


Serves 8-10

Ingredients:


For the crust
• 1 ½ cups all purpose flour
• ½ cup confectioners sugar
• ¼ teaspoon salt
• 1 stick + 1 tbsp unsalted butter, very cold, cut into pieces
• 1 egg yolk, lightly whisked

    For the lemon cream
• 1 cup sugar
• Grated zest of 3 lemons
• 4 eggs
• ¾ cup lemon juice (4-5 lemons)
• 2 sticks + 5 tbsp (10.5 oz) unsalted butter, room temperature, cut into pieces

Directions:

 

 

For the crust:

§         To make the crust, put the flour, icing sugar and salt in a food processor and pulse to combine.

§         Add the butter and pulse until the mixture is coarse, around the size of oatmeal and/or peas.

§         Add the egg yolk a little at a time, pulsing after each addition and then processing in 10-second pulses once the whole egg has been added until the dough forms clumps.

§         Turn the dough onto a flat work surface and lightly knead the dough until all dry ingredients are just incorporated.

§         Butter a 9 inch fluted removable-bottom tart pan.

§         Press the dough into the pan evenly. Freeze for about an hour.

§         Preheat the oven to 375°F.

§         Butter the shiny side of a piece of aluminum foil and fit it tightly against the crust.

§         Bake for 25 minutes.

§         Carefully remove the foil, and press the dough down gently if it has puffed using the back of a spoon.

§         Return it to the oven for another 8 minutes, or until it is beautifully golden brown.

 

For the cream:

§         Before you start the lemon cream, have a candy thermometer, a strainer and a blender at hand.
§         Simmer a little water in a saucepan.
§         Put the sugar and lemon zest in a large heatproof bowl.
§         Off the heat, rub the mixture together with your fingers until the sugar is moist, grainy and aromatic.
§         Whisk in the eggs and then the lemon juice.
§         Set the bowl over the pan of water and whisk continuously until it reaches 180°F
§         As it gets close to temperature it will start to thicken. This can take up to 10 minutes, so be patient!
§         Remove the cream from the heat and strain it into the blender.
§         Discard any solids. Let the cream stand at room temperature for about 10 minutes, or until it cools to 140°F
§         Turn the blender on high, and add the butter a few pieces at a time.
§         Scrape down the sides to incorporate the butter.
§         Keep the machine on for 3-5 minutes once the butter is in to ensure a perfect lemon cream
§         Pour into an air-tight container and refrigerate for at least 4 hours (it will keep in the fridge for up to 4 days).

 

Assembly:

§         When you are ready to assemble the tart, whisk the cream to loosen it and spoon it into the tart shell.

§         Serve the tart or refrigerate as needed.
