In a large bowl, mix dough ingredients and knead until you obtain a homogeneous dough.
In a 22cm pie pan, roll out the dough using your fingers.
Bake for 20 minutes at 180ºC until golden and crisp.
Meanwhile, prepare the filling: mix pumpkin purée with double cream, whole milk, sugar, eggs and spices.
Blend to combine all the ingredients.
Pour the filling into the pre-baked pie pan and bake for 10minutes at 200ºC. Then, reduce the oven temperature to 180ºC and continue baking for another 35-40 minutes until the filling is set but still slightly wobbly in the centre.
Allow to cool completely before removing from the pan.
Serve with whipped cream and lime zest.
Tip: double the proportions of the filling if you want to make it fuller.
