Method
1. Preheat oven to 140°.
2. Mix the digestive biscuit crumbs with the melted butter and brown sugar and press into a 25cm/10” glass pie dish.
3. For the filling, mix the egg yolks with the condensed milk then stir in the lime juice and zest.
4. Pour the mixture onto the digestive biscuit base and bake for approximately 40-45 minutes or until it’s slightly firm.
5. Remove from the oven and leave to cool before covering and storing in your fridge.
6. Whisk the double cream and caster sugar together until firm then add to a star-nozzle piping bag and create decorative rosettes around the outside edge of the pie.
7. Decorate the top with some finely grated lime zest and serve.
