Lettuce, as a common green leafy vegetable, is loved for its crisp taste and rich nutrition. Whether as a main ingredient in salads or a side dish in cooking, lettuce can add a fresh green color to the dining table.
Many people often encounter the problem of lettuce turning black and losing its crispness when stir frying, which makes the originally crisp and delicious lettuce no longer attractive.

In fact, as long as you master the correct processing methods, stir fried lettuce can completely maintain its color and taste. Below, I will share the correct steps for stir frying lettuce, so that you can make restaurant level delicious lettuce at home.
1、 Selection and Cleaning
Choosing fresh lettuce is crucial. Fresh lettuce leaves should be compact, brightly colored, and free of spots or withered yellow parts. After purchasing, it is necessary to thoroughly clean it. Peel off the lettuce piece by piece and gently rinse under running tap water.
Ensure that every leaf is washed clean and avoid residual soil or pesticides. After cleaning, use kitchen paper towels to absorb moisture or use a centrifugal vegetable and fruit dehydrator to spin dry to avoid excess moisture causing the lettuce to become soft and flat during the frying process.
2、 Preprocessing techniques
Pre treating lettuce before frying can greatly improve the quality of the finished product.

  1. Iced treatment: Place the washed and drained lettuce in the refrigerator compartment and chill for at least half an hour. The purpose of doing this is to make the cell tissue of lettuce more compact, and the stir fried lettuce will be more crispy and refreshing. In addition, low temperature can also inhibit the oxidation process and prevent lettuce from quickly turning black during frying.
  2. Quick blanching: Quickly blanch the chilled lettuce in boiling water for a few seconds, then immediately remove and immerse it in ice water. This step is called "soaking water", which can kill surface bacteria while locking in the color and nutrients of lettuce, keeping it green during the frying process.
  3. Seasoning and marinating: Before stir frying, you can put lettuce slices into a bowl, sprinkle a little salt and a little white vinegar (or lemon juice), gently mix well, and let it stand for a few minutes.
    Salt can help lettuce release excess water, while sourness can further enhance the color of lettuce, making the stir fried lettuce more vibrant and tempting.
    3、 Stir frying techniques
    The key to stir frying lettuce lies in the control of heat and time, as well as the appropriate oil temperature. Here are some tips for stir frying lettuce:
    -Use high heat to stir fry quickly, which can quickly lock in the moisture of lettuce and maintain its crispness.
    -The oil temperature should not be too high to prevent the surface of lettuce from burning and the interior from not being fully cooked.
    -Try to minimize flipping during the frying process to avoid damaging the fiber structure of lettuce and causing it to lose its crispness.
    -Before serving, add an appropriate amount of garlic, ginger or chili to enhance the flavor.
    By following the above steps, you can stir fry a plate of lettuce with a green color and crispy texture.
