Any one of a number of varieties of a citrus fruit, native to Southeast Asia, now widely cultivated, especially in temperate climes. There are both bitter and sweet varieties, as well as many hybrids such as ortaniques. Sweet oranges are eaten fresh, used in sorbets and granitas, squeezed for their juice, or their aromatic rind can be used in baking or added to meat and fish stews and soups. Bitter oranges are usually cooked and used in marmalades or dishes such as duck à l’orange, used for their oils or to make orange flower water, made from a distillation of the blossoms. Buy oranges that feel heavy and have tight skin and store at room temperature for a day or so, then store in the fridge after this time.
