Aussies love meringues and these combine perfectly with an American Key Lime Pie! Am I selling ice to Eskimos here??? This lovely, creamy Key Lime Pie is adapted from a Delia Smith recipe and I've added an optional meringue topping made from the left-over egg whites. The secret to this pie's velvety texture is not to overcook it. Otherwise it's simple to make and you can, of course, omit the meringue topping if time is an issue. Another benefit of this pie is that it can be made well ahead - or even frozen - so it's a great dinner party or picnic recipe. Try it!
