1, lettuce with a paring knife shaved skin (to the white part of the stem shaved clean, affecting the texture), with a silk wiper rubbed into the silk, add 5 grams of salt mixing marinated for about half an hour.

2, pickled look (pickled time is not too short, the lettuce water are pickled out of the taste of crisp, if not pickled through, the back of the mix will still be out of water, affecting the flavor).

3, add green onion oil, half a teaspoon of salt and sugar and mix well (no green onion oil with sesame oil or olive oil can also be).
