There are times I where you sometimes get random ingredients in your fridge and totally don't know what sort of dish you should make out of it. That's how I felt with the blueberries and lemon I had. Not that it was a bad combination, but the blueberries I bought were sour and lemon is sour (duhh). It would be a super sour cake but I thought ah what the heck! Let's just do this and it is now in my list of favourite cakes. What an experiment huh?
