Key Lime Squares Made From Pie Filling.

I have some graham crackers 
left over from making campfire S"mores
 with the Grandkids, this Summer, and

 I decided to use them up 
in a crust for some squares.
I also had some Key Lime Pie Filling
in the pantry.
So I put them together
to make these Key Lime Squares.

This pie filling is a Canadian product,

made in Mississauga, Ont.

FOR THE CRUST:
20-22 Graham cracker squares
 I  crushed them in a plastic bag with a rolling pin.
2 tbsp. sugar
1/2 tsp salt
1/3 cup butter

Preheat oven to 375deg.F.

Mix Graham cracker crumbs, sugar and salt. 
Stir in melted butter.
Mix well.
Press firmly on the bottom of a 9 inch square pan.
Bake for 7 mins. 375 deg. F.
Cool before filling.

FOR THE FILLING:
(the directions of the box)

2 egg yolks
1/3 cup cold water
1  Key Lime Pie filling pouch contents.
2 cups hot water
1 tbsp butter

In a saucepan add 2 slightly beaten egg yolks.
Add 1/3 cup cold water and 
the pouch contents and whisk until smooth.

Add the 2 cups of hot water and mix.
Cook over medium-high heat stirring continuously, 
When bubbles first break the surface, 
continue to stir for 30 seconds.

Remove from stove top and stir in the 1 tbsp butter.
Cool 5 minutes stirring twice. 

Pour into the prepared cooled square pan.
Optional...I grated a lime and sprinkled it on the top.

Cool on the counter 3 hrs. before serving,
torture....

Key lime trees don't grow in this colder region of North America.
In fact, the fruits are not available in most stores here.
Only the ordinary limes are available. 

I'm embarrassed to admit that I didn't know why
they were called "Key Limes" so I did a search,  
and got my answer.

(source, wikipedia)

The Key Lime is smaller, seeder and higher acidity, stronger aroma, and thinner rind that that of the Persian lime. The key lime is valued for its unique flavour compared with other limes.

The name is derived from its association with the Florida Keys, where it is best known as the flavouring ingredient in Key Lime Pie. 

(I've learned something today and the squares are sooo delicious.)
I prefer them to lemon squares. One piece is not enough.
