Technically it is a sausage very similar to Catalan Botifarra but the boil is thicker and stuffed in the large intestine of the pig. The bull blanc is the most popular and is also known by the names of 'white bishop', 'bufa', 'thick white sausage' and, in the Girona region, 'peltruc' or 'paltruc'.
It is a pork sausage made from the bladder, large intestine or stomach, stuffed with minced and pickled meat from the pig itself, with recipes that vary quite a lot depending on the producer, but where different types of meat and the little ones of the pork are always used.
The result is a beige sausage with a granular texture, with a mild taste very similar to that of white sausage. It is usually eaten with bread with tomato, in hors d'oeuvres or salads.
It is sold in many charcuteries throughout Catalonia.
Made from meat, fat and pork offal, it is a very energetic food, rich in proteins of high biological value and B vitamins. Within a varied and balanced diet, occasional consumption is totally recommended.
