Ingredients
- 1partly baked 9-to-9½-inch tart crust in a pan with a removable bottom (recipe)
- 1lemon, scrubbed and dried
- 1½cups/300 grams sugar
- 2large eggs, at room temperature
- 3tablespoons/24 grams cornstarch
- 4ounces/113 grams unsalted butter (1 stick), melted and cooled
- Confectioners’ sugar, for dusting
Preparation
- Step 1
Center a rack in the oven, and heat it to 325 degrees. Place the crust on a baking sheet lined with parchment paper.
- Step 2
Cut the lemon into thin slices, and discard the seeds. Toss the slices and sugar into the bowl of a food processor, and whir for 3 minutes, scraping the bowl as needed, until smooth. With the machine running, add the eggs, one at a time, and then, when they’re incorporated, the cornstarch followed by the melted butter. Remove the bowl, and rap it against the counter a few times to pop some of the bubbles in the mixture. Pour the batter into the crust.
- Step 3
Bake the tart for 45 to 55 minutes, until the filling is puffed and lightly browned — don’t be concerned if the top cracks. If you tap the side of the pan, the filling should seem firm; if it jiggles just the least bit in the center, that’s fine. A toothpick poked into the center — be gentle — will come out clean. Transfer the tart on the baking sheet to a cooling rack. Leave until it reaches room temperature. The tart can be served now or chilled (it will keep in the refrigerator overnight).
- Step 4
Just before serving, dust the top with confectioners’ sugar.

Just started making this dough and I find it way too dry and almost unworkable after taking it out of the Cuisinart. Did anyone else have the same problem?
Can I use all of oil or another oil in place of the butter?
Please use ripe, thin-skinned lemons (or limes, yum). Meyer lemons are wonderful in this. Those thick, knobby-skinned, full-of-pith regular lemons in the grocery store do NOT a good tart make.
My second time making this, for Easter. I had a hard time getting the lemon peel bits smooth—a blender might work better. Watch the timing at the end—mine went from jiggly over half the surface to slightly overcooked in just a few minutes.
Definitely don't just use jiggle factors as an indicator of being cooked-- I pulled mine a little before browning on top and it was raw ultimately. D efinitely do no jiggling AND Brown. I also used pith(the whole lemon) as directed in instructions and it was still perfect. Maybe it was my organic lemon.
I really like making the Atlantic Beach Pie crust for this cake.
