The value of offal cooked in a pan
Fried pork liver, whose calorific value is quite high, is an excellent second course, as well as a very important food product for anemia. And if you add onions with sour cream in the pan, then it is impossible to break away from the dish until the plate is empty.

The nutritional value of the by-product largely depends on what other components the main ingredient will be combined with. So, if, for example, you cook the liver in sour cream and tomato sauce, then ultimately the nutritional value will be approximately 150 kcal per 100 g.
Boiled offal value
Boiled pork liver, the caloric content of which of all the options described in this article is the least, is useful for children. If you cook this offal by immersing it in boiling water, then the finished dish will have only 120 kcal. For comparison: fried - 205 kcal. But boiled pork liver, the calorie content of which makes it a valuable dietary product, is inferior in usefulness to a steamed dish. Therefore, the ideal option for cooking pork liver for kids is just steaming the product.

Before you buy pork liver in a store or on the market, you need to carefully examine it, while you should pay attention to color and smell. It should smell pleasant: not a sour, but a sweetish aroma. If it has an unpleasant odor, it means that the liver is stale and not worth buying. The color of the product should be uniform - not too light, but also not dark. The surface should be smooth, elastic, without any dried up spots and stains.
