ok, I will just post it here. But don't you lot tell anyone about my super secret recipe!
I assume you can all make a basic vanilla cupcake. If not, I can post a recipe for that too.
Once they're baked, simply cut a hole out of the middle as if you were making fairy cakes. Add the filling, then top with meringue.
The filling is as follows:
2 egg yolks
1 Can of condensed milk
Juice of one or two lemons
beat the egg yolks into the condensed milk, then slowly fold in the lemon juice till it sets. It goes quite thick. Don't worry if it looks like the lemon wont fold. It will. Just keep adding a little at a time till the mixture goes thick. Don't add any more juice after it sets or your mix will go runny again. Also, you may not need the juice from two lemons. It depends how tart the lemons are.
This is so much easier than making a lemon curd, but you could do that if you prefer.
To make the meringue, simply beat your egg whites till they're fluffy, then add several tablespoons of castor sugar. You may need an extra egg white. I used 4 whites to do a dozen cupcakes and had just enough. Again, it depends how big the eggs are. Try to use extra large ones.
You will have too much of the filling for 12 cupcakes, so you may want to just eat the leftover.
When you've put your meringue on the top of your filled cupcakes, you can either put them in a really hot oven for a couple of minutes, or under a griller, or you can blow torch them if you have one. You don't really want to cook the meringue too much. I think it's nicer if it's fairly soft still. If you cook it too much, the other issue is drying out the cake.
Have fun, and show pics!
