It got rave reviews at our Easter dinner and would be wonderful for Mother's Day, too! I can't think of a better combo than shortbread and lemon curd. The crunchiness of the shortbread pairs wonderfully with the creamy filling. It really is SO good.
Lemon Curd Shortbread Tart
1 cup sugar
1 tsp. vanilla
1/4 tsp. salt
1 3/4 cup flour
3/4 cup almond flour
Lemon Curd:
1 cup sugar
zest of 2 lemons, finely grated
1/2 cup lemon juice
2 egg yolks
3 eggs
1/2 cup butter, cubed
For the lemon curd, combine the sugar, lemon juice, egg yolks and eggs in a large microwave-safe bowl. Whisk well until combined. Stir in the butter cubes. Microwave for 45 seconds on high power, then stir well. Continue microwaving in 45 second increments, stirring well after each heating, until the curd coats the back of the spoon or reaches 175 degrees. This process will take 5-7 minutes, likely. Stir in the lemon zest. Let cool on the counter top while you assemble the tart dough. You can also make this in advance and refrigerate it until you need it.
(Alternatively, you can use chilled butter and do this process in the food processor. Just don't pulse too much or you won't get nice clumps of butter. You want to create a streusel.)
Spray a 9-inch tart pan with baking spray. Press about 2/3 of the dough evenly up the sides and covering the bottom of the pan. Place the bowl with the remaining dough into the refrigerator.
Position a rack in the middle of the oven. Place a sheet pan on the rack and preheat the oven to 325 degrees. Place the tart pan on the sheet pan and bake for 10-14 minutes, until the crust is just beginning to firm up and turn golden brown on the edges. Remove the sheet pan from the oven and allow the tart to cool for 10 minutes, then spread 1 1/4 cups of the lemon curd evenly over the bottom of the crust. (You won't use all the lemon curd. You could use the remainder over ice cream, on scones, to make a trifle, etc!)
Remove the remaining dough from the refrigerator. Grab a handful of the crumb mixture and gently squeeze it in your hand, then sprinkle it over the lemon curd, breaking it up into large crumbs as you go. Repeat until all of the crumb mixture is used up.
Return the tart (on the sheet pan) to the oven and continue baking until topping is firm, crisp and lightly golden in color, and the filling is not "jiggly," about 30-35 minutes. Transfer to a wire rack and let cool to room temperature.
