What is a Blood Orange?

food cooking

The blood orange is a darker orange to red-fleshed orange that has been popular for numerous years in Europe. It has now gained popularity in the US, and there are blood orange crops grown in Florida and San Diego. The exterior of the blood orange is a rose-tinted orange color. Depending upon variety, the skin color may be lighter or darker. The surprise comes when one cuts open the orange to reveal its pink to dark crimson flesh.

There are several varieties of the blood orange. These are the Tarocco, the Sanguinello, and the Moro. Of these, the Tarocco has the greatest popularity in Europe and is grown primarily in Italy. It may not always have the highest red coloring however, and some Tarocco blood oranges resemble more traditional oranges. However, in taste the Tarocco is often considered superior to the other varieties.

The Sanguinello is grown in Spain, and is an almost seedless variety. It tends to have a deeper red color. The Moro is most commonly grown in the US and tends to have the darkest flesh. If one is really going for that deep crimson in juices or dishes prepared with the blood orange, the Moro may be the best choice.

The coloring of the blood orange differs from the typical orange because it has an additional pigment called anthocyanin. Anthocyanin can be found in purple and red flowers, and other fruits. For example, the Fuji and Red Delicious Apples owe their deep red exterior to the pigment.

The blood orange is also celebrated for its taste. A ripe blood orange is very sweet and mellow. Some ascribe subtle flavoring hints of raspberry and strawberry to the orange. However, others simply describe the blood orange as identical in taste to a sweet regular orange.

These oranges are definitely taste pleasers, and are exceptional in presentation for a variety of dishes. An orange salad made with blood oranges and “orange” oranges can be a beautiful dish. Orange juice made with the blood orange is a lovely color and heightens the drama of a smoothie or a mimosa.

Slices of blood oranges can garnish vanilla ice cream, or provide an essential ingredient to a fruit salsa. Blood oranges used in tarts are also beautiful. Most recipes for blood oranges are usually sweet in nature, as used in either desserts or drinks. However, blood oranges can also make excellent garnishes for savory dishes.

If you have not yet tried a blood orange, it is definitely not to be missed. You may find yourself falling in love with these sanguine beauties, both for their taste and unusual appearance. The Moro blood orange is typically available in the US from late December to April or early May.

One of my moro blood oranges busted open before ripening. What would cause this?

I live in San Diego and I have a blood orange tree. I don't know what strain it is but all of them are seedless and 50% are pink to crimson on the inside.

@ Anon7007:

actually, a "tangelo" is a cross between tangerine and pomelo. the blood orange is most likely just a mutation of a regular sweet orange.

I live in Tucson, AZ and bought a small Moro blood orange tree at a nursery in Oct 2004. I kept it in the pot until Spring. The fruit barely turned red and was not very sweet. I planted it at my new house at an elevation of 2600 feet, and within 2 years, we were getting dozens of large sweet oranges from about Dec 20 to Feb 1, depending on the weather. I wait until the outsides turn red, then taste test 1 before picking for juice &/or eating. The tree is on the SE side of the house where the winter temps fall to about 25F. I cover it whenever the nights go below 28F. One night was 20F and even with a cover, many of the leaves fell off, but there were no flowers or fruit. I've purchased blood oranges at AJ's Fine Foods around Xmas time, and you can also order them online in California. Good luck with the tree!

Hi I recently bought a blood orange plant (I haven't planted it yet) it is a "Citrus Sinesis" and we have cut open the fruit and it is the normal orange colour of a normal orange not red. The skin colour looks ripe but it is not sweet and the flesh not red so I wonder have I been sold something else. I would be interested to hear anyones comments thanks. Sandy.

Maybe I have not looked hard enough, but it seems that regular supermarkets do not carry blood oranges. One recent winter, when I visited the East Coast of United States I have seen blood oranges in one market, but on the West Coast I have not seen them at all.

But what I did discover recently is a very good orange, dark pink on the inside, not as dark as blood orange, but darker then the regular orange. It sort of reminds me of a grapefruit, however, it is very sweet, juicy and absolutely delicious. It goes by the name of Cara Cara.

Is this is a naturally occurring fruit or a cross between different species?

Editor's reply: That's a great question! Many believe that the blood orange is possibly an ancient hybrid between the pomelo and the tangerine, most likely originating in Sicily. There are many other newer types of blood oranges, such as the Moro.
