Preheat oven to 350 degrees
If you are making your own *pie crust, make in advance and refrigerate before preparing the fruit.
Clean the apricots well, cut them in half. Remove the pits and give them a rough chop. Place in a large bowl
Zest the lime and juice it. Add it and the sugar, vanilla, cornstarch, cinnamon and salt to the bowl. Mix to combine.
Roll out the bottom pie crust and place in the bottom of the pie plate. Pour in the fruit mixture. Dice the butter and add to the top of the fruit.
Roll out the second crust and place it on top of the pie. Crimp the sides - this is to prevent the liquid from bubbling out.
If you're going to glaze the crust, now's the time to do it. Add milk to the egg and whip. Using a pastry brush, lightly brush the mixture over the top crust.
Sprinkle the crust with about a 1/2 teaspoon of cinnamon & a teaspoon of sugar. Cut several 1 inch slits into the top of the crust. This allows the steam to escape when it's cooking.
Bake for one hour at 350 degrees.
