But I do have a favorite, and it is so ridiculously simple that when I made it last week I actually kicked myself for waiting so long since the last time I gave it a spin. Where are my priorities? Seriously. I won’t slip up again.
This is such a great one to have in your files because it doesn’t demand a lot of your grocery list: just one whole lemon. That right, peel, pith and all. And because you only have to buy one, you can go ahead and splurge on the gorgeous Meyers around right now (but fortunately, this works with any kind of lemon). Everything else comes from common ingredients: butter, sugar, eggs and a parbaked tart shell that promises not to shrink up on you but when it all comes together… you won’t believe how much came from so little. Or how quickly an entire tart can disappear. Don’t say I didn’t warn you.

Whole Lemon Tart
Loosely inspired by a version from the Paris pastry shop, Rollet-Pradier
[Updated recipe as 1/26/11] I fixed it. I fixed the tart. Let me explain. I’ve been making this tart for years; it’s the perfect lemon tart, as far as we’re concerned. Not too achingly sweet. Comes together in a breeze. No juicing, no zesting, no stressing. I probably made it 5 times in my old apartment, with nary a problem. But I received mixed reviews from commenters, many who reported overflowing tarts that never set and always seemed sticky. When we moved to our new apartment, I made the tart in my newer oven and then I knew what everyone was talking about! Trouble, trouble. But all of that is old news because I fixed it. I looked to my lemon bars as guidance and realized that the recipe was sorely lacking in enough eggs to set the tart. Previously, there was 1 plus 1 yolk. Now there are 4 (yes, four) large eggs, just like lemon bars. And it’s a dream. I’m eating a piece right now. It’s not even lunchtime. I never learn.
I’ve also drastically streamlined the directions — the whole tart is now made in the food processor, as I always have at home. The butter doesn’t need to be softened or melted. You’ll have the filling made and the tart out of the oven in 45 minutes. This is the perfect dessert to bring to a dinner party.
1 partially baked 9-inch Great Unshrinkable Tart Shell, or your favorite sweet tart shell
1 average-sized lemon (about 4 1/2 ounces; 130 grams), rinsed and dried*
1 1/2 cups (300 grams) sugar
1 stick (4 ounces or 115 grams) unsalted butter, cut into chunks
4 large eggs
2 tablespoons (14 grams) cornstarch
1/4 teaspoon table salt
Center a rack in the oven and preheat the oven 350°F (165´C). Place the tart shell on a baking sheet, which you can line with foil or parchment paper to make any spills a breeze to clean up.
Slice the lemon into thin wheels, remove any seeds, and toss the rounds — lemon flesh and peel — sugar and chunks of butter into the container of a food processor. Process, scraping down the sides of the container as needed, until the lemon is thoroughly pureed. Add the eggs, cornstarch and salt and pulse until the batter is smooth.
Pour into prepared tart shell. It will fill it completely but if due to slight variances in tart pans, egg sizes, lemon sizes or crust thickness, you have too much, do not pour it past the top of of your crust or it will become difficult to unmold later.
Bake for 35 to 40 minutes or until the filling is set. You can test this by bumping the pan a little; it should only jiggle slightly. In my oven, I find that the point at which the filling is set is also when it starts to get very light brown on top.
Let cool on rack, unmold tart pan and serve. I actually prefer this tart completely chilled, which makes it a great dessert to make in advance of a dinner or party.
* Meyer lemons are the first choice here. They’re milder with thinner skin. But if you know that you do not mind a stronger lemon and rind kick, feel free to use a regular lemon, which will have a stronger flavor and a higher proportion of skin to flesh. If your lemon is not 4 1/2 ounces (Meyers often weigh in closer to 4 ounces) go ahead and cut a wedge out of a second one to keep the lemon flavor in balance with the sweetness of the tart.
