Real duck blood is dark red, while fake duck blood is generally red brick.

2. Look at the toughness

After a piece of duck blood is drained with a napkin, if it becomes as tough as plasticine, it is fake duck blood. Fake duck blood has a gelatinous texture and is not easy to break, and most of the cross sections have honeycomb-shaped holes; The true duck blood is dark red, with sparse pores, and it is easily broken.

3. Smell

Compared with fake duck blood, real duck blood has dark color, good elasticity and a strong fishy smell.

4. According to the taste

The fake duck blood section has large pores and is chewy to eat, while the real duck blood is smooth in texture, small in pores and tender and smooth in taste. Moreover, the more the fake duck blood is rinsed, the more tender the real duck blood is, and even it will be broken with chopsticks. With a pair of "golden eyes" to distinguish between true and false, I hope everyone can eat delicious duck blood smoothly.
