Blood orange
Citrus × sinensis · Rutaceae · also known as Sanguine, Arancia rossa, Moro, Tarocco
A sweet orange whose flesh flushes crimson to near-black when cold nights trigger anthocyanin pigments. Sicily's most celebrated citrus, prized for a berry-edged flavor and a color no ordinary orange can match.

- How to eat
- Eat and juice like any orange; the reward is the color and a berry-edged flavor, best shown off in salads, sorbets, and cocktails.

A blood orange only bleeds where nights are cold — the anthocyanins that redden its flesh form in response to a chill, which is why Sicily's Etna-side groves produce the deepest color and warm-climate versions stay plain orange.

How to select & store
Picking a ripe one
Choose heavy fruit for its size with firm skin; exterior color is a poor guide — some of the reddest flesh hides under a mostly-orange rind, and a russeted skin is fine. Weight signals juiciness.
Storing it
A week at room temperature, up to two weeks refrigerated. The color often deepens in cold storage as anthocyanins develop.
Practical uses
🍽️ Culinary
- Eaten fresh and juiced — the ruby juice is a showpiece
- Blood-orange salads with fennel and olive, a Sicilian classic
- Sorbets, cocktails (the negroni's cousin, the "blood-orange" spritz), and marmalades
- Segments over cakes and salads for drama
🌿 Health & traditional
- Anthocyanins add antioxidants beyond the usual citrus vitamin C
🎎 Cultural
- Sicily's blood oranges (Arancia Rossa di Sicilia) carry protected-origin status, ripening in the volcanic soils around Mount Etna
- Etna's cold nights are what turn the flesh red — the same fruit grown in warm climates stays orange
Eating blood orange: what to know
What regular consumption looks like
Blood orange is a nutritious everyday fruit, best enjoyed as part of a varied diet. 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. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
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, Blood 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.

Cut into a blood orange and the drama is immediate: flesh streaked crimson, or in the deepest Moro types, a red so dark it verges on black. It’s an ordinary sweet orange with an extraordinary secret — anthocyanin pigments, the same antioxidants that color raspberries, which appear only when the fruit ripens through cold nights.
Sicily’s signature citrus
The three great cultivars all come from Sicily, ripening in the volcanic soils around Mount Etna: Moro (the darkest and most berry-flavored, verging on raspberry), Tarocco (sweeter, milder, and among the most vitamin-C-rich oranges of all), and Sanguinello. Together they hold protected-origin status as Arancia Rossa di Sicilia, and Etna’s chilly nights are the un-fakeable ingredient — the same trees grown in warm climates produce fruit that stays plain orange inside.
More than a pretty color
That berry undertone makes blood orange a cook’s favorite. Sicilians build a classic winter salad of sliced blood orange, shaved fennel, olives, and good oil; the ruby juice becomes sorbet, spritzes, and a showpiece breakfast pour; and the segments bring color to cakes and salads that a normal orange can’t. Don’t judge by the skin — some of the reddest flesh hides beneath a mostly-orange, even russeted, rind.
When to catch it
Blood orange is a deep-winter fruit, roughly December to April, its color often deepening the longer the cold lasts. For a bitter winter cousin used in marmalade, see the Seville orange.
