Whole Lemon Tart
Just before Mario's Italian Lemonade closed for the season, I hung out at the stand eating my peach lemonade and chatting up the night manager. I was inquiring if it was really true they use the entire lemon making their base, he indicated the lemons were thrown into a blender with some peel reserved for the mixing in later. I have to admit to being rather dubious on this whole lemon claim until yesterday.
Culinary Historians this month featured Dorie Greenspan who co-wrote
Baking with Julia (Child). Dorie has written a new book,
Paris Sweets, Great Recipes from the City's Best Pastry Shops. Dorie's talk had been presented at the Smithsonian, which featured her careful narrative using visual images of bakeries and cakes to support her ideas. (I am very dismayed by public talks where the power point visuals guide a talk -- or worse yet, images with lots of words which the presenter READS to you.) Near the close, she had a 3-minute video clip of Master Baker Poulaine making cookie dough by hand just weeks before his unfortunate death.
Every Culinary Historians meeting concludes with a tasting of recipes from either the author's books or foods which compliment the talk's theme. This month was a series of desserts from Dorie's book. For the first time, I made one of the desserts: four whole lemon tarts for the simple reason I am comfortable making pies.
The lemon tart's base is Pate Sucree (Sweet Tart Dough), which there are many variations. For this recipe, you will need a partially baked 9 inch tart shell, then you add the filling:
Whole Lemon Tarte
adapted from Paris Sweets by Dorie Greenspan
1 average-sized lemon (about 4.5 ounces), rinsed and dried
1-1/2 cups sugar
1 large egg
1 large egg yolk
1-1/2 tablespoons corn starch
1 stick unsalted butter, melted and cooled.
Preheat oven to 325 degrees Fahrenheit.
To remove the seeds, slice lemon thinly and extract any seeds. Drop lemon slices into the blender with the sugar. Process for 1-2 minutes.
In a small bowl, add the egg yolk and whole egg and lightly whisk. Add the lemon puree and blend gently. In a small custard cup, add 3 tablespoons of this lemon mixture, then add the cornstarch and mix until well blended. Return cornstarch-lemon puree to the lemon-egg mixture along with the cooled melted butter, then whisk lightly to blend. Pour lemon mixture into the tart shell.
Bake tart for 20 minutes, then increase temperature to 350 degree Fahrenheit to bake for another 15-20 minutes or until the filling is bubbly and lightly browned. Cool at least 20 minutes before removing. Tart is ready to be served at room temperature.
Tart is best served on the day it is made.

I don't usually like lemon flavored cheesecake, lemon bars or lemon meringue pie or just about any lemon in desserts. Yet, I like lemonade, lemon ices, lemon in my tea, lemon chicken and so on. I did like this lemon tart beyond my expectations. The use of a full lemon, which includes the skin's essential oils, really brings out a full range of flavor which the juice alone does not provide. The slight carmelization of the sugar on the upper crust also intensified flavors.
All this effort, or lack of really, got me thinking more about Mario's claim to use the whole lemon in their base. Or how simply pureeing lemon with sugar could make an excellent lemonade either frozen or beverage with some dilution by water required naturally.
From making this tart this weekend, I have found a new culinary tool: whole lemon puree. Just now I flipped over to google to find a recipe for lemon curd which uses 1/3 cup lemon juice. I'm inclined to try it two ways: juice and whole lemon puree. From the sparkling flavors in the lemon tart, I predict the whole lemon variant will be a likely improvement over juice.
For your consideration with my compliments.
