Key Lime Pie

Happy Pi Day everyone! And what an exciting one it is (3.14.15).
This pie is perfectly seasonal – being both a pie (for Pi day) and a fabulous shade of green which is appropriate for St. Patrick’s Day next week 🙂
It’s also very easy to make and a delicious way to take advantage of the abundance of limes we are lucky to have at this time of the year.

Ingredients (serves 8-10)
135g digestive biscuits, finely crushed
60g caster sugar
75g butter, softened
1x 400g can sweetened condensed milk
125ml fresh lime juice
2 teaspoons grated lime zest
2 eggs, separated
Green food colouring (optional)
300ml thickened cream

Method
Preheat oven to 170°C. In a shallow 20-23cm pie dish, press combined biscuit crumbs, sugar & butter into the base and up this sides, making a small rim.

In a medium bowl, whisk condensed milk with lime juice, zest and egg yolks until the mixture thickens. Add 1-2 drops of green food colouring.

In a small bowl with electric mixer on full power, beat egg whites to stiff peaks. Gently fold into lime mixture.

Pour lime filling into the biscuit crust and smooth the top.

Bake the pie for 15-20 mins or until lime filling is just firm.

Cool pie in this dish and then refrigerate until chilled, approximately 3 hours.

Whip cream in a small bowl until stiff peaks form. Pipe a border of cream around the edge of the pie and top with h lime wedges if desired. Enjoy!
