Step 1

Preheat the oven to 180 Degrees C (355 F).Place the biscuits in the bowl of a food processor and pulse until they resemble fine breadcrumbs.Add the melted butter to the biscuit crumbs and process until well combined.

Step 2

You will need a 23 cm (9 inch) pie plate. Our pie dish has a depth of about 5 cm (2 inches) and we take the biscuit crumb up to the 4 cm (1.5 inches) mark approximately. Tip the biscuit and butter mixture into the pie plate. Using the back of a dessert spoon, or the base of a flat-bottomed glass, press the mixture over the base and up the side of the pie plate.

Step 3

Place the pie crust into the pre-heated oven and bake until golden, about 8-10 minutes.Remove the crust from the oven and set aside to cool completely. This will take about 15 minutes.

Step 4

Whisk the condensed milk and the egg yolks together in a large bowl. Add the lime and lemon juice and continue to whisk until they are well combined.

Step 5

Carefully pour the filling into the cooled pie crust and bake until the centre of the pie is just set - about 15 minutes.

Step 6

Set the pie aside and allow it to cool completely. This will take about 1 hour.Cover the pie with cling wrap and place it in the refrigerator until cold; for at least one more hour.Once chilled, add cream or decorations and serve. Like a lot of pies, the first slice is the hardest to remove. We recommend using a sharp knife for clean cuts, and a spatula to help remove the slices.

Step 7

Whisk the cream and icing/powdered sugar until it forms soft peaks. Top the pie with the whipped cream or place it into a piping bag and pipe some rosettes around the edge of the pie. Decorate with lime slices or zest.
