Katie's post here over at Apple and Spice reminded me that I too had that particular baking tin. I bought it a while ago (in the sale ;-)) and had completely forgotten about it, but thought at the time of purchase that it would make great individual cakes in a more interesting shape than cupcakes. So it was decided - lemon and lime, and a drizzle too.
Lemon and lime drizzle cakes
In the meantime, make the syrup.
