"Oranges and lemons say the bells of St Clement's"

So, a variation on the lemon-blueberry cupcakes of study leave... Orange and Lemon cupcakes.

Changes made:
-Using all self-raising flour instead of half and half - they now rise and look like proper cakes!
-Not melting the butter, but creaming it with the icing sugar for the icing - it looks about a hundred times better, much less like a glaze.
-Used far more zest, because I did a whole lemon and then half a ruddy big orange on top.
-Yellow food colouring in the icing, to make it more cheerful!

And obviously, they are now orange flavoured. I like them much, much better than the lemon ones!

(Also I still haven't read the Aeneid. Can you tell?)
