First, the varieties of lettuce

The Romaine lettuce plant is slender and tenacious, adaptable even in the cold season, and its leaves are bright green, shiny, with a hint of yellowish color. When eaten, the taste is crisp and tender, but there is a hint of bitterness.

As the name suggests, the shape of the knotted lettuce resembles a ball, and at first glance, many people confuse it with large spinach. Its leaves are thick, chewy when eaten, and the taste is still very delicious.

Glass lettuce
The color of glass lettuce is dark green, and its taste may not be the best of the lettuce, but it is the most nutritious, so people call it "the queen of the vegetable kingdom"

Lettuce picking tips
1 Look at the leaves
See if the color of the lettuce leaves is emerald green, the lighter the leaves, the more crisp it is to eat, and the darker green color of the dish is chewed with slag. The better the lettuce leaves, the crisper they are, and you can feel it by pinching the leaves with your hand. And the leaves are not very thick, and the leaf surface has a seductive luster.
2 Look at the stem
The stem is white and bright in color, and the incision during harvesting does not turn into a rusty appearance, so the lettuce is fresh lettuce. Due to the oxidation of air, the incisions and leaves of the sativa will become as if they are rusting.
3 Watch the vegetable ball
When choosing knotted lettuce, you should also pay attention to choosing vegetable balls that do not break the belly and do not produce moss. If the vegetable ball is broken, it means that moss has begun to grow inside, and such a lettuce is an old dish.
How to wash lettuce
Lettuce is mostly eaten raw. The cleaning of lettuce is a very important thing. There are two main ways to wash lettuce:
1. Clean water soaking washing method. Rinse off the surface with clean water, then soak in pure water for about 10 minutes, then rinse with clean water. In this way, the residual pesticides on the vegetable leaves can basically be removed.
2. Taomi water cleaning method. Taomi water contains alkaloids, which can be neutralized by acid and alkali and effectively reduce pesticide residues on vegetables. Rinse the lettuce and soak it in rice water for about 10 minutes, then rinse.
Of course, if you want to keep fresh for a period of time, then do not dip into water after buying it, and directly wrap it in plastic wrap and put it in the refrigerator. Lettuce is extremely sensitive to ethylene and should be stored away from apples, pears and bananas to avoid inducing reddish brown spots.
