A return to a subject that at one time was threatening to be an obsession, but that I haven't tackled for a while. There is a similar recipe to this one in my book, but with digestive biscuits. I reckon that this 3:1 biscuit:butter ratio works as well, or better, than the 2:1 I have recommended previously.
You need a 20cm flan dish or tin. Serves 6 to 8.
150g ginger biscuits
227ml double cream (that is the size of the Yeo Valley pot)
200g cream cheese (a standard pack)
397g condensed milk (a standard tin)
1 lemon, zest and juice
1 lime, zest and juice
Whizz the biscuits to crumbs in a food processor. Melt the butter over a low heat in a small saucepan. Tip in the crumbs, stir until thoroughly coated. Grease your dish or tin, and tip in the biscuit mixture, spreading it over the surface and compacting it with the back of a spoon. Put the dish into the freezer for 30 minutes to an hour.
Whip the cream until it stands in soft peaks. You have to be careful to stop as soon as it gets to this stage: from there, it moves rapidly to complete stiffness.
In a separate bowl, whip together the cream cheese and condensed milk. Some recipes suggest you can thicken the milk by whipping: that does not work for me, perhaps because I am lazy or impatient. No matter. Mix in the lemon and lime zest and juice.
Fold the cream into the cheese/milk/citrus mixture. Pour the filling on to the frozen (or very cold) base, cover, and return to the fridge for at least a couple of hours before serving.
