Key Lime Pie

key 2


I was sent a postcard from Florida nearly thirty years ago with this recipe for Key Lime Pie by a friend who knew I would much prefer a recipe on a postcard to a postcard of an alligator.

I’ve made the recipe many times, sometimes with lemons and sometimes with limes.

1 tin (400gm) sweetened condensed milk

1/2 Cup lime juice

1 Cup sour cream

1 Tblspn grated lime rind

green food colouring (about two drops should be enough)

250ml whipped cream

250 grams plain sweet biscuits, (as always, I prefer Arnotts Marie biscuits)

150 grams melted butter

Crush the biscuits. I’ve finally worked out the best way to do this and it involves a plastic bag with a seal and a rolling pin.


Mix the butter into a bowl with the crushed biscuits, then press into a pie tin and refrigerate.

Stir the sweetened condensed milk and lime juice together. Fold in the sour cream, lime rind and food colouring.

Pour into the pie crust and refrigerate. Serve with whipped cream.
