- 1 lb. key limes, zested and juice, making about 1 cup juice
- 1/2 cup water
- 1/4 cup sugar
- 1 almond tart dough, recipe follows
- 1 egg, beaten
- 4 egg yolks
- 1/2 cup sugar
- 1 cup condensed milk
- six 4 x 2 inch rectangle tart pans

1Using a zester, grate lime peels (green part only),s topping before you get to the bitter white cottony pith.
Cut zested limes in half and juice them, setting them aside for later use.
2Fill small pan with water and add lime zest. Bring to a boil, then drain using a fine sieve. Repeat this step two more times to get rid of any remaining bitterness of the lime zest.
3Put 1/2 cup of water, sugar and lime zest in pan and cook over medium heat for 15 to 20 minutes til liquid turns into thick syrup.
4Remove pan from heat and set aside til it cools to room temperature.
Working on well floured surface, roll out dough to a thickness of about 1/8 inch.
5Cut six 6 inch x 4 inch rectangles out of dough and put them in the pans, using your fingers to gently press dough into bottom and up sides. Using a fork, make several holes in dough. Trim excess edges of dough, roll into ball, cover with plastic wrap and freeze for future use.
6Cover pans with plastic wrap and refrigerate for 15 minutes. Preheat oven to 375.
Put six 8 inch x 6 inch rectangles of parchment paper over dough. Weight down paper with pie weights or dried beans. Bake for 15 minutes. Remove pie weights or beans and parchment paper, brush dough with egg and bake for another 3 minutes. Remove plate from oven and place on wire rack til it reaches room temperature.
7Reduce oven temperature to 350.
Meanwhile, in large bowl, mix together egg yolks, sugar, condensed milk and reserved lime juice using a whisk.
Pour lime juice mixture into crusts and bake for another 20 minutes.
8Transfer pans to wire rack and let cool for 30 minutes.
Decorate top of each tart with 1 tablespoon of the lime zest and 1 Tbsp. of the syrup. Refrigerate for an hour before serving. The tarts can be refrigerated for up to two days after preparation.
