When I cut into a lemon I can't help but give it a good sniff. It's the same with lime and grapefruit. There's something about that citrus smell that I just can't wait to inhale; especially if it's a drizzly day. I also love tropical flavours at this time of year: coconut, passion fruit, mango, you name it! Combining a bit of citrus and a bit of tropical was the idea here so I set about baking some lemon and coconut flapjacks.
