Zesty Lime Squares

*Zesty Lime Squares*
Makes 12

These are very similar to good old fashioned lemon squares, but have been updated to use lime juice and zest to create a refreshing and delicious bar.  I just love the flavour of limes.  Can you believe that before I moved over to the UK I had never tasted a real lime.  My only brush with it had been through eating green jello!!  My goodness what I have missed!  I am so glad that I discovered the true taste of lime!

7 ounces unsalted butter, cut into chunks
2 cups all purpose flour
1/4 cup icing sugar
1 egg, lightly beaten
6 large eggs
1 1/2 cups superfine sugar
1/2 cup all purpose flour
1/2 cup fresh lime juice (The juice of about 4 limes)
the finely grated zest of 4 limes

Icing sugar for dusting on finished bars

Grease and line the base of a 9 inch square baking tin with some baking paper.  Place the butter, icing sugar, flour in the base of a food processor.  Blitz together until crumbly.  Add the beaten egg and blitz until a soft dough forms.  Press this dough into the base of the prepared tin.  Place in the refrigerator to chill for half an hour.

Pre-heat the oven to 180*C/350*F.  Bake the base in the pre-heated oven for 20 to 25 minutes.

Whisk the eggs together in a bowl.  Whisk in the sugar, flour, lime juice and zest.  Whisk together until well combined.  Pour this mixture over the cooked base.  Bake for an additional 20 minutes, or until the filling is set and the mixture is light golden brown on top.  Remove from the oven and allow to cool completely in the tin on a wire rack.

When cooled, remove from the tin, cut into bars and dust with icing sugar before serving.
