A basket of oranges is a basket containing 1 to 5 oranges. The best use for a full basket of oranges is to pay a farmer to watch over a Maple tree. Putting oranges in a basket will instantly place all oranges in your inventory, up to 5, into the basket, thus it is possible to have incomplete baskets if you had less than 5 oranges in your inventory at the time.
The number of oranges stored in the basket is displayed in the item's name, in parentheses: Oranges (5), for example..
Oranges may be collected through a player-grown Orange tree at level 39 farming, and may be found in gnome shops.
An orange may be sliced into orange slices by using a knife on it.
Oddly enough, a basket of oranges weighs less than 5 oranges and a basket.
