Vegetables have been commonly used in baking cakes and muffins. A common one is carrots to make one of my fave - carrot cake. Recently I also found out about adding zucchinis (or courgettes) to brownies and cakes. I also found some recipes advising using beetroot in chocolate cakes.
I am wondering what other vegetables can be used in baking? Is there anything I should watch out for? Does a certain vegetable pair well with another ingredient?
