I have an obsession with using whole citrus fruits to make cakes.
For one, it's quicker to chuck the whole fruit in the blender than juicing, but by keeping the skins, you also retain vitamins, minerals and a whole heap of fibre.
It's no lie that the skins are the best part! The pith can be quite bitter (don't eat whole citrus raw!), but when cooked and paired with sweetness, salt and fat, the bitterness diminishes.
The resulting cake is rich and comforting in flavour, with a squidgy crumb and a crispy exterior.
I picked these mandarins up from Taupo's new Countdown in Kokomea Village as an "Odd Bunch" pack; $4.50 for 1 kilogram. Bargain!
