1. First, we put the whole pig tongue in cold water. After the water is boiled, we boil it for 2 minutes, then take it out and put it in a cold water basin. This will cool down quickly and scrape off the tongue coating better, then scrape off the tongue coating on the surface of the pig's tongue with a kitchen knife and rinse it clean.

2. Then take another pot, add a bowl of clear water, put the pig tongue in the pot with cold water, and then put a bag. If there is no package, it will be opened separately: star anise 1, pepper 10, a small piece of cinnamon, 2 tsaoko, 2 fragrant leaves, dried tangerine peel 1, rhizoma kaempferiae 3g and ginger 6544.

3. Then cover the pot cover, bring the pot to a boil over a high fire, then turn the fire down for about 40 minutes, and insert it with chopsticks. You can easily insert the pig's tongue and it will be cooked.

4. Then turn off the fire, fish the pig tongue into the basket, let it cool naturally for a while, and dry the water. It's not very hot now, don't wait until it gets cold, just see that there is no water.

5. When the water is dry, slice the pig's tongue with an oblique knife and put it on a plate. Because I was in a hurry today, I put it directly on the plate. It's best to find a bigger basin, stir it and put it on the plate, so that it can be stirred better.

6. Then sprinkle a little coriander on the cut pig tongue, pour a little sesame oil, a little old vinegar and a little soy sauce, and stir well. It's delicious. Give it to a friend you like.
