When you combine the words ‘blood’ & ‘cake’ you’d be forgiven for rendering images of gory Halloween creations, however from January to early March the word ‘blood’ actually becomes rather appetising.
Now, to my knowledge there are very select times in life where blood is willingly consumed, usually this comes as part of a fry up, in the form of black pudding (a type of British blood sausage made using pig’s blood for those of you wondering). Delicious as this dark, iron rich sausage is though, it’d be no good in cake.
The late winter ‘blood’ I’m referring to, actually relates to a fruit that derives its namesake from its characteristic blood-like colour, of course I’m talking about the blood orange.
Originating in Sicily and Spain, the blood orange’s distinctive ruby flesh is due to the presence of anthocynanins, a pigment most commonly found in flowers and berries. Due to this pigment, it also contains far more antioxidants than your regular orange.
This blood-red colour within the fruit will only develop during the colder temperatures of winter nights, this colour can sometimes seen on the exterior rind of the fruit too. This means that the blood orange only has a very short season in late winter, being at their sweetest during January & February.
With a sweet, slightly less tart flavour than other oranges, their unique flavour has distinct hints of berry amongst the usual citrus notes. The skin is slightly tougher & harder to peel than that of regular oranges, making it somewhat of a reward when you reach its sweet, juicy fruit (as someone who take ages peeling oranges anyway, it’d damn sure better be worth it!).
With many uses in things like juices, candied fruits & marmalades to flavoured oils & dressings. The Sicilians use it in a winter salad alongside fennel bulbs and olive oil. Here the arancia rossa di Sicilia (or the red orange of Sicily) has been given protected geographical status (at present, there is no such status for the black sausage of Britain, but we’ll see).
The “Tarocco” variety of blood orange is one of the most popular in Italy & indeed the world because of its sweetness & juiciness, this is the one that you will most commonly find in shops & markets at this time of year. The “Tarocco” is commonly known as the half-blood orange (anyone else imagine a magical world of oranges?) because not all of its flesh is pigmented with deep red hues like other varieties. It also has the highest vitamin C content of any orange variety grown in the world (what benefits still remain when added to a cake is yet to be discovered).
With such a naturally occurring beauty about them, it’d be a shame not to flaunt it & with blood oranges not readily available in the supermarkets (as with most seasonal delights unfortunately), these beauties were hard to get hold of in the middle of rural Wales. Persevere though & support your local green grocers who always have a plethora of unusual & quality goods not found elsewhere.
My reward is a sweet, citrusy, nutty sponge topped with a little bit of Italian sunshine. Sticking with the theme of my Italian “Tarocco” oranges, I’ve opted to make my sponge using ground almond as opposed to flour, this not only adds a depth of flavour & texture to the cake but orange & almond is just such a classic pairing. Making this an upside-down cake makes sure that the blood orange is the star of the show, allowing it’s striking, deep crimson colour to burst through before it’s topped with a blanket of ruby syrup made from its own juices. If that doesn’t cure the winter blues, I don’t know what will.
