The key lime pie, as the heading says, has a ginger biscuit base that goes beautifully with the rich creamy texture of the key lime tangy cream filling. The recipe is for 12 to 16 people but can be reduced to what amount you want. This recipe makes three 22cm key lime pies.
The mixture of the ingredients, double cream, condensed milk and limes will most certainly serve 12 people, but for the biscuit base you may want more depending on what thickness you prefer.
Instead of ginger biscuits you can use plain or sweetmeal digestive biscuits.
