Because the production process of foie gras itself is troublesome and the cost is relatively high, many restaurants actually use duck liver instead of foie gras, although the menu is awkward. Because when we say foie gras in French, we mean thick liver instead of goose, so using foie gras and duck liver in authentic French dishes is not cheating customers. Moreover, duck liver tastes similar to goose liver, but the cost of duck liver is much lower, because ducks grow faster than geese.
Foie gras is generally made by frying, because it can ensure that the foie gras is complete when eaten. When frying, put a piece of butter in the pan. When the butter melts, put it in and fry it on both sides. Then you can cook. If the taste is weak, you can put some salt or dip it in sauce. However, the fat content and protein content of foie gras are relatively high. If you usually have fatty liver or high blood pressure, obese people had better eat less of this food.
If you think it's difficult to eat only foie gras, you can also try to make foie gras bibimbap, which is also a very popular dish at home and abroad. Fried foie gras with some vegetables you like, and then with a bowl of rice and some special sauces is also a very rich meal.
