Lemonade fruit

The lemonade fruit is a hybrid citrus fruit found in Australia and New Zealand. A cross between a navel orange and a lemon, it was first cultivated in the 1980s and grows in subtropical regions of the two countries, notably Queensland in Australia and Northland in New Zealand. The fruit has a similar appearance to limes, but yellows as it ripens. The fruit is segmented, and can be eaten readily; its low-acid content gives it a sweet taste similar to the orange, but with a flavour not unlike a mild lemon.^[1]
