Lovely Lime Squares (with a pistachio-lime-graham cracker crust!)

Since it feels like summer out in Montreal, I thought I'd post the recipe for these incredible lime squares that I made last weekend. Honestly, I liked these way better than any lemon square I've ever had (and I have an amazing recipe for lemon squares!). I think it's the lime zest and pistachio nuts in the graham cracker crust that make them so special... trust me, they're delicious!

Read on for the recipe....

Lovely Lime Squares

For the crust:
2/3 cup unsalted pistachios
1 cup graham cracker crumbs
1/4 cup sugar
1 Tbs lime zest
1/4 cup butter

Lime Topping:
4 eggs
4 egg yolks
1 1/3 cup sugar
1 Tbs lime zest
pinch of salt
1 cup freshly squeezed lime juice
1/2 cup butter, cut into pieces

Icing sugar for dusting

1. First grease an 8 inch square baking tin, and line the bottom with parchment paper.
2. Next make the crust. In a food processor grind the pistachios, graham cracker crumbs, sugar and lime zest until finely ground. Next add in the butter and pulse until well-combined.
Press into the bottom of the baking dish to form the crust and bake in a preheated oven at 350 degrees for 10-12 minutes (until slightly golden). Once finished, set aside to cool.
3. In a saucepan, mix the eggs, egg yolks, sugar, salt and the other tablespoon of lime zest. Add the butter and heat over medium-low, stirring constantly, until the butter melts and the mixture begins to thicken... approximately 7 minutes.
4. Pour the mixture over the crust and bake at 350 degrees for 15 minutes (until the lime filling is set).
5. Allow to cool completely before slicing into 2-inch squares. Sprinkle with powdered sugar prior to serving. Enjoy!
