Key Lime Tart

Alas...lots of cooking and very little writing do not a food blog make! I'm here to remedy this, finally. I think I have a few recipes that are worth sharing - and eating.

To start, my first attempt at using a pastry bag. Not overly impressive. But if you keep in mind it was completely without research or practiced technique, I think it looks cute enough. Plus, piping whipped cream doesn't hold it's shape quite as well as a buttercream frosting.

This whipped cream topped a creamy lime custard tart with a spicy gingersnap crust. Resembling key lime pie, but without real key limes, I admit it's only a Lime Tart. But, as a defense, Cook's Illustrated says that using Persian limes (supermarket limes) are both much easier to juice, as they're larger, and the taste difference is negligible. I don't know if I truly buy that these limes are interchangeable. I've had real key lime pie and it is superb, after all. But, this plain old Persian lime tart was easy and tasted fabulous!

Lime Tart with Gingersnap Crust
(recipe adapted from Cook's Illustrated,
The Best Recipe)

1 1/2 cups gingersnap crumbs, ground in a food processor from gingersnap cookies
2 Tbsp sugar
4 Tbsp butter, melted
dash of cinnamon

Pulse the gingersnaps in a food processor until uniformly ground. Add the sugar and cinnamon. Pulse a few more times to incorporate. Remove the gingersnap crumbs to a mixing bowl. Stir in the melted butter until well combined. Press the crumbs evenly over the bottom and up the sides of a buttered tart pan. Using plastic wrap helps prevents the crumbs sticking to your fingers.

Bake the crust at 325 degrees F for 15 minutes. Remove from the oven and let cool for 15-20 minutes. You don't want to pour the filling into a piping hot crust.

1 (14 oz) can sweetened condensed milk
1/2 cup fresh lime juice, strained
4 egg yolks
2 Tbsp grated lime zest

Whisk together the egg yolks and lime zest in a medium bowl for several minutes. (Cook's Illustrated says this turns the yolks a pale green, but I didn't find this to be true.) Whisk in the condensed milk and then the lime juice. Let this mixture rest just a few minutes to thicken.

Once the crust has mostly cooled, pour the filling into the crust. Bake at 325 degrees F for 15-17 minutes or until the filling is almost set, but still wobbly in the center. Cool again until the tart is at room temperature, then refrigerate for about 3 hours until well chilled.

Whipped Cream:
1 cup heavy whipping cream
3 Tbsp confectioner's sugar

Beat the heavy cream on medium speed with an electric mixer until soft peaks form. Gradually beat in the sugar until smooth and stiffer peaks form. Using a pastry bag with a small star tip, pipe the whipped cream over the tart in whatever way your technique allows!

This is one of my absolutely favorite American desserts, and darn - I forgot to eat it this summer in the USA, AGAIN! One of these years I will. They are pretty simple to make, I remember, although your lovely whipped cream topping looks elaborate!
