Winter citrus fruits such as navel oranges, lemons, limes, ruby grapefruit and imperial mandarins are all in season now, and taste great. Navel oranges are a great “eating orange”, and are much easier to peel than the summer valencia oranges. The imperial mandarins are from Queensland at the moment, are easy to peel, but do contain a few pips. When the Victorian varieties start next month, they should have less pips.
