1. Snow bean bubble is about 2-3 times its volume.

2. Pig's trotters are clipped with hair clips, so it's best not to burn them, and be patient.

3. First boil a pot of water, put the pig's trotters in, keep the fire, and then open it for about 1 minute, then pick up and dump the waste water.

4. Put the scalded pig's trotters, soaked snow beans, three thumb-sized ginger (flattened with a knife), a section of green onion and 15 pepper into the pot, add a proper amount of cold water, cover and stew for about 1.5 hours, and add salt and monosodium glutamate to taste.

If you stew meat in a pressure cooker, the water will boil and turn into a small fire. Just stew for 40 minutes, saving time.
