GBBO/BBC Key Lime Pie

Ryan's Key Lime Pie from BBC Food website

I'm not going to discuss how to make this pie as you can find the recipe on the BBC website (I believe this one is Ryan's recipe):

I actually made this soon after Ryan made it on GBBO and was highly praised for it and I used the American Key Lime Pie recipe from the book The Great British Bake Off How to Turn Everyday Bakes into Showstoppers. So anyway, when I was shopping for the ingredients I looked up the recipe online. It wasn't until I was about to start the pie that I noticed the recipe in the book asked for double cream. Well, the online didn't ask for double cream so I thought I had better read the both recipes properly. What I discovered was that the the recipes are fairly similar (except for the double cream) but the BBC one is baked and the GBBO one isn't. 

So now I have made both and both are absolutely delicious! My only tip is that you will only need 2 egg whites for the Italian meringue. I used the four that the recipe asks for and it makes way too much. I even made macrons with it and still had some left. I would just freeze the other two and use them next time you want to make a pavlova.
