About
Citrus australis, the dooja, round lime, Australian lime or Australian round lime, is a large shrub or small tree producing an edible fruit. It grows in forest margins in the Beenleigh area and northwards, in Queensland, Australia.
Citrus australis is a tree up to 20 m (66 ft) tall. Fruits are spherical or slightly pear-shaped, 25–50 mm (0.98–1.97 in) across, with a thick green or yellow skin and pale green pulp. The 1889 book The Useful Native Plants of Australia records that "The fruit, which is an inch and a-half in diameter and almost globular, yields an agreeable beverage from its acid juice."
Uses
Its nutritive properties include: "energy 91 g, moisture 74.8 g, protein 2.2g, nitrogen 0.35 g, ash 0.8 g, dietary fibre 6.7 g, carbohydrates 15.5 g, Ca 46 mg, Cu 0.2 mg, Fe 0.5 mg, Mg 24 mg, K 270 mg, Na 4 mg, Zn 0.1 mg, niacin 0.37 mg". Due to this, it is still used in cooking today in Australia. The fruit can be eaten raw, and is acidic in nature. However, it is more commonly used in cooking for making marmalades or as lime flavouring. The peels can also be cut to make an accent for pastas, or can be ground for a subtle integration into the sauce. It can also go well with seafood. The flowering season is restricted to spring, and fruits are ripe from November to March when the skin turns greenish-yellow.
