Indulge in the tangy sweetness of this Best Ever Key Lime Pie with a buttery crust and topped with fluffy Italian meringue.
Crust
200g crushed digestive biscuits
80g butter
Zest of 1 lime
Filling
2 tins condensed milk
250ml soured cream
Zest of 2 limes
180ml lime juice
Italian Meringue
180g sugar
1ml salt
100ml water
3 egg whites
Preheat the oven to 160°C and grease an oblong loose bottom pie dish (±36cm by 12 cm)
Combine the crushed biscuits, lime zest and the melted butter to make the crust
Press the mixture onto the base and sides of the pie dish – press firmly with a spoon to make sure it sticks to the sides.
Refrigerate for 30 minutes before adding the filling.
To make the filling
Combine all the filling ingredients in a bowl and mix well till smooth and creamy
Pour the mixture into the chilled crust
Bake in the pre-heated oven for ±20 minutes (do NOT let it brown)
Cool completely and top with Italian meringues and garnish with more lime zest and lime slices
Italian Meringue
Dissolve the sugar and salt in the water in a saucepan on medium heat and bring the sugar syrup to the boil. Do not let it boil before all the sugar has dissolved.
Use a sugar thermometer and boil the syrup to 118 °C – when the temperature reaches 112 °C start beating the egg whites so long. The egg whites must be beaten to the stiff peak stage.
When the syrup reaches 118 °C, remove immediately from the heat and slowly add it to the beaten egg whites while you continue to beat at high speed. The whole process should take about 3 minutes and then you can continue beating the hot meringue until it cools slightly. (the meringue must still be warm when you use it)
Spoon into a piping bag and pipe onto the cold key lime pie
