Lemon Curd Tart with an olive oil & almond crust

This picture doesn't do this tart any justice at all. This is the best lemon tart I've had (if I do say so myself!). My husband says this should become my "go to" dessert.

This tart is dead simple to make - even for the non-baking type.

Ingredients & Preparation (from Epicurious, Original from Gourmet, 2008)

Active time: 45 min Start to finish: 4 hr
Servings: Makes 6 servings

For tart shell (I doubled this part of the recipe since many reviews on Epi recommended that you do so)

• 4 tablespoons almonds with skins, toasted and cooled
• 1 1/2 cup2 all-purpose flour
• 1/2 cup confectioners sugar
• Big pinch of fine sea salt
• 1 stick cold unsalted butter, cut into 1/2-inch cubes
• 2 large egg yolks
• 6 tablespoons fruity olive oil (preferably French)

For lemon curd

• 3 large lemons
• 3/4 cup granulated sugar
• 2 teaspoons cornstarch
• 2 whole large eggs plus 2 large yolks
• 1/2 stick unsalted butter, cut into 1/2-inch cubes
• 2 tablespoons fruity olive oil (preferably French)

Equipment: a 9-inch round tart pan with removable side; a small offset spatula

Make tart shell:

Preheat oven to 425°F with rack in middle.

Pulse almonds with flour, sugar, and sea salt to a fine powder in a food processor. Add butter and pulse until mixture resembles coarse meal with some small (roughly pea-size) butter lumps.
Add yolk and oil and pulse until just incorporated and a very soft dough has formed.

Spread dough evenly over bottom and up side of pan with offset spatula. Chill until firm, about 30 minutes.

Bake shell until golden brown all over, about 13 minutes. Transfer to a rack to cool completely, about 30 minutes.

Make curd:

Grate enough zest from lemons to measure 1 tablespoon, then squeeze 3/4 cup juice from lemons.

Whisk together lemon zest and juice, sugar, cornstarch, whole eggs, and yolks in a medium saucepan and bring to a boil over medium heat, whisking constantly. Boil, whisking, 2 minutes.
Remove from heat and whisk in butter and oil until smooth.

Assemble tart: Pour lemon curd into cooled shell and chill until set, at least 2 hours.

Cooks' notes: Tart shell can be made 1 day ahead and kept, loosely covered, at room temperature. Assembled tart can be chilled up to 4 hours.
