Seville orange
Citrus × aurantium · Rutaceae · also known as Bitter orange, Sour orange, Bigarade, Naranja amarga
The bitter orange too sharp to eat raw but essential to marmalade, to the sauce bigarade, and to orange-blossom water. One of citrus's foundational hybrids, valued for rind, aroma, and acidity rather than sweetness.

The trees lining Seville's streets drop tonnes of bitter oranges each winter that are shipped to Britain to become marmalade — a fruit Spain grows for beauty and Britain buys to eat.

How to select & store
Picking a ripe one
Choose firm, heavy fruit with rough, deeply colored, very fragrant skin. A brief winter season (mainly January) is when Seville oranges appear for marmalade-making.
Storing it
A week or two refrigerated. The peak use is immediate marmalade; the juice and grated zest freeze well for year-round cooking.
Practical uses

Eating seville orange: what to know
What regular consumption looks like
Seville orange is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of fibre (about 4.5 g per 100 g), which supports digestion and satiety. It is a good source of vitamin C (about 50 mg per 100 g), supporting immune function and helping the body absorb iron from plant foods.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Seville orange contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.
Safety notes
- Bitter (Seville) orange contains grapefruit-like furanocoumarins and can interact with some medications; the concentrated bitter-orange extracts (synephrine) sold as supplements are a separate cardiovascular concern.

The Seville orange is proof that a citrus doesn’t need to be sweet to be indispensable. Too sour and bitter to eat out of hand, it is one of the foundational citrus hybrids (pomelo × mandarin) and the essential fruit behind marmalade, duck à l’orange, and orange-blossom water.
Bitter by design
Its thick, high-pectin pith is exactly what makes Seville marmalade set so beautifully — the bitter British breakfast classic exists because of this fruit and its brief January harvest. Beyond the jam jar, its sharp juice cuts the fat of duck in sauce bigarade and forms the backbone of Latin American mojo marinades; its fragrant peel flavors triple sec, Curaçao, and Grand Marnier; and its blossoms are distilled into orange-blossom water and neroli oil. The ornamental sour oranges lining the streets of Seville itself are grown for beauty and scent — Spain’s beautiful, inedible-raw crop that Britain imports by the tonne to turn into marmalade. For its sweet-fleshed relative, see the ordinary orange; for a fellow aromatic bitter citrus, bergamot.
