Citrus aurantium, also known as the bigarade orange, Sevilla orange or bitter orange, is a widespread citrus tree. It is spread to many (sub)tropical parts of the world, where it is cultivated for its special fruit. This fruit is used in cooking, for its oils, perfumes, solvents and medicine. It is well known as the main component of English marmalade.
The bitter orange tree has a remarkable appearance with its glossy green leaves and fragrant white flowers. These flowers are famous for their aroma - which is why they are often used in perfumes and aromatherapy. The fruit of Citrus aurantium is generally round with a somewhat rough, thick skin. This skin has a strong, bitter taste and is often used in a large variety of culinary goods. Among these are Belgian Witbier, compotes, spirits, cuisines, candy, desserts and more. The flowers and peel of the bitter orange are ingredients in herbal medicine. They are used as a stimulant and an appetite suppressant.
Citrus aurantium is not only a worthwhile addition in the kitchen, but also a source of inspiration for many painters and gardeners.
