2, turn on the faucet and peel the yam under the stream of water, which will allow the water to wash away most of the slime, and naturally you won't be exposed to as much phytolacca.
3, before peeling, boil the yam with skin in boiling water for a while. You can also poke a few small holes in the surface and then quickly heat it in the microwave.

You can also cook the washed yam in cold water with the skin on, and then peel it after it cools down.
