The Seville is a ‘sour’ orange as opposed to a ‘sweet’ orange. This is a medium to large, thick-skinned orange with high levels of bitterness and acidity. The majority of Seville oranges are used to make marmalade, though they are also used for juice production, jam, crystallised fruit, liqueurs, and the skin yields very good citrus oil.

Manufacturers of marmalade have only one chance each year to stock-up on supplies of Seville oranges which are harvested in Spain in January and February. To keep production going throughout the year, they buy a large proportion of the crop and freeze it until needed in the factory.
