For the crust, place the crushed biscuits and sugar in a bowl and stir to combine, making a well in the center.

Spoon into your pie dish and press firmly and evenly into the base and sides of your dish with a measuring cup or flat glass.
Place in the oven and bake for 10 minutes until lightly golden.
Remove and set aside to cool.
Filling

Notes
Graham crackers: The perfect base for this pie with their light and whole wheat flavor. If you are unable to source graham crackers, a great substitute is digestive biscuits.
Lime juice: The very core of this recipe is the fresh lime juice which adds a bright and zesty flavor to the custard filling. Key lime juice is best, but you can replace with any other fresh lime juice.
Sweetened condensed milk: This creates a sweetness alongside the lime juice and is an essential to any key lime pie.
Why we bake the filling: Baking helps set the crushed base and means liquid of the filling doesn't soak through that crushed biscuit base meaning it's nice and firm and can't become soggy.
If you don’t want to bake the pie: Simply lower the amount of lime juice to 80 milliliters or less than ⅓ of a cup
Make in advance: You can make the pie up to 1 day before serving, but this is best served within 2 hours of topping with whipped cream and consumed the same day or within 1 day, as leftovers.
Pie dish: The pie dish used here is 18 cm / 7 inch which is around average, though a substitute would be a deep tart tin.
