In the market, pig blood and duck blood are often confused, and sometimes consumers may inadvertently spend the money of "duck blood" to buy "pig blood". To make sure you get the product you want, here are some ways to distinguish between pig and duck blood:
First, distinguish by smelling the smell. Pig blood has a slight smell of blood, while duck blood basically does not smell of blood after being treated at high temperatures, but will waft out a duck fragrance. This is due to differences in protein denaturation and aroma release between the two at different temperatures.
Second, look at the nutrient content. Pig blood is a good protein**, with twice as much protein as pork, and is also rich in minerals such as iron, zinc, calcium, phosphorus, and essential amino acids. Duck blood is also nutritious, containing a lot of minerals such as iron and calcium, making it a healthy ingredient.
Again, it is distinguished by the touch and texture. The texture of pig blood is relatively firm, and the stomata on the cut surface are larger, making it chewy to eat. The texture of duck blood is smoother, the pores are smaller, the taste is delicate and silky, and it will crumble when you pinch it lightly.
Now that you know how to tell the difference between pig and duck blood, let's look at how to cook these ingredients to maximize their flavor.
Pig blood, due to its firm texture and rich protein, is suitable for cooking into dishes with strong flavors, such as spicy pork blood, pig blood tofu soup, etc., which can mask the fishy smell of pig blood while enhancing its delicious taste.
Duck blood, due to its delicate taste and rich minerality, is suitable for cooking into light soups or hot pots. In the soup, duck blood can absorb the essence of the soup and become tender and delicious; In hot pot, duck blood can maintain its delicate texture, adding rich layers and nutrients to the hot pot.
In conclusion, both pig and duck blood are nutritious ingredients that can be made with the right identification and cooking methods. Hopefully, the above information will help you avoid spending the wrong money and enjoy your food while getting a balanced diet.
