Precautions for purchase:

1. Look at the appearance of ribs:

Fresh ribs are bright red, preferably pink, not too red or too white.

2. Smell the ribs:

The smell should be fresh pork and slightly fishy. Once there is other peculiar smell or bad smell, don't buy it, it is easy to be a bad ribs.

3. Press the ribs:

Press the ribs with your fingers. If you press hard, the meat on the ribs will quickly return to its original state. If it collapses, the meat quality will be worse. Then touch the surface of the ribs with your hands. The surface is a little dry or slightly wet and does not stick to your hands. If you stick your hands, it's not fresh ribs. The meat feels tight to the touch.
