3, lettuce purchase skills

1 Look at the leaves of lettuce. The leaves are green and fresh, not dry, yellow and withered. This is a common observation angle when people choose leafy vegetables, and lettuce is no exception. Under normal circumstances, if the leaves of lettuce are very green, it can be said that lettuce is very fresh, fresh lettuce has a lot of water and tastes good, so freshness is the first element of good lettuce.

2. Grab the stem of lettuce. As we all know, lettuce has a lot of fresh water, but as long as it is left for a long time, the water gradually loses. At this time, there is a way to tell, that is, holding the stem of lettuce, you can find that if it is fresh, the stem of lettuce is usually very tall and straight, but once it is not fresh, the stem of lettuce will look soft, just like a withered plant, and it can't keep very tall and straight.

3. Look at the cross section of lettuce. There are two kinds of lettuce, one is very thick and the other is very thin, which can be seen from the cross section. Generally speaking, the skin is thin and looks very clear between the skin and the meat. This kind of lettuce tastes crisp when it is fresh, and the skin doesn't take up much weight. Lettuce with thick skin sometimes needs to be peeled very thick and contains silk, but this kind of lettuce with thick skin locks water well and is not easy to wither. Can be placed for a few days, according to the need to choose.

4. Look at the color of lettuce meat, whether it is hollow. Some lettuce looks good, especially when it is fresh, but it can't stand scrutiny. If you look at the meat of lettuce, you will find that some are dark green and some are blue and yellow. This kind of green food is naturally dark green and needs attention. And lettuce, although the root looks good, as long as you cut it deeper, you will find it is hollow. This kind of lettuce is definitely not good. As for what's bad, I can't say clearly, but it won't be too delicious.
