First, the types of foie gras are different. In fact, French foie gras, as a top ingredient, must be screened many times from raw materials, and foie gras should also be taken from the specific variety of "Southwest Grey Goose", and other geese can't be made into French foie gras. This southwest grey goose, also known as Lande Goose, originated in Lande Province in the southwest of France. It is not an ordinary meat goose, but a special kind of "fat-dried" goose, mainly for extracting goose liver. The nutritional value of this goose is far more than that of ordinary meat goose.
However, the foie gras in our country is generally common meat goose. In our eating habits, we prefer to eat external parts such as goose meat, but we rarely eat this viscera, and the quality of the foie gras of common meat goose is far less than that of French foie gras, which can only be regarded as a very common ingredient, and few people will eat it.
Second, the farming methods are different. The traditional way to feed geese is to feed them with feed. When they are hungry, they will eat feed. The feed is generally common cereals, vegetables, etc. It takes about three months for the average goose to grow and mature. If it is stocked, the breeding cycle will be longer.
However, the demand for foie gras in France is relatively large, and the requirements for the quality of foie gras are also relatively high. If it is an ordinary duck that eats feed, its foie gras is relatively small. Therefore, many farms will come up with a way to put the broken food into the goose's stomach through a tube. It may take many times to instill food a day. Too many times and the range of activities of the farm is small, the goose can't digest these foods at all. After a long time, it will form a "fatty liver".
The weight of such foie gras can even reach 600-900 grams, which is severe fatty liver, but often such foie gras can be regarded as high-quality foie gras. If the weight of foie gras is not up to standard, it can't be made into foie gras at all, so this kind of "fatty liver" is very popular with the French.
In our country, geese are basically raised at will. Even in farms, we will not force the geese to be fed food, because we mainly eat goose meat instead of foie gras, and the geese have high freedom of movement. This kind of goose meat tastes more delicious, and the breeding cycle is relatively long, usually in half a year or more. The main purpose is to make the geese grow more meat.
Third, eating foie gras is a symbol of "status" In the middle and late period of France18th century, foie gras was once given to the king as a tribute to taste, and the king was amazed after eating it, so it became a dish in the imperial cuisine. Since then, foie gras has become famous, and many upper-class people began to taste it. Later, eating foie gras has become a symbol of "status" and they can afford to eat it.
In China, foie gras is a very common food, even no one eats it at all, not to mention eating foie gras is a symbol of "status". Moreover, foie gras is rarely sold in our country, even if it is sold at a very cheap price.
