How to clean up the black inside the lotus root hole.

If it is not broken, there is generally no mud, why does the inside of the lotus root turn black? What turns black is broken, and it turns black and is not mud. You can't wash it off if it's black, it's the juice that comes out of the lotus root, and it's not broken.

There is also a situation where the yellow inside of the lotus root is not mud, and this is rust and not mud. Just like the gourd also has this yellow rust spot inside, if there is mud in the broken lotus root is easy to clean, cut it open and rinse it with tap water to clean it. There is no technique required to wash the lotus root, even if it is cut and washed by hand.

Generally, we try not to dig the lotus root when we dig it, it is not easy to sell it, that is, when washing the lotus root, we can not break the lotus root skin, and it is easy to turn black if it is broken.

First of all, the first step is that when we buy the lotus root, the first thing we need to do is to clean all the mud on the outer skin. Then we peel off the skin and cut the lotus root into small slices. This is mainly to allow us to observe the small holes of the lotus root more intuitively, and see if there are enough stains in them.

At this time, we put the lotus root that has been cut into slices into a large bowl, and then put more water in the bowl. Be sure to put more, because at this time, water is to play a soaking function for lotus roots, so it is always no harm for everyone to put more. The next step is to put some salt and white vinegar in the water.

This kind of thing can be found everywhere in our kitchen, so it is also a more convenient method, then we stir everything evenly, soak the lotus root in the water for about three minutes, and when we are finished, we can find a lot of sludge floating on the surface of the water. At this time, what we have to do is to put the remaining lotus root under the faucet, flush it with a large amount of running water, and completely wash the sediment inside, and our lotus root will basically be washed at this time. The next thing we want to tell you is that there are actually some tips when choosing lotus roots, that is, if we want to use lotus roots to make soup, then it is best to choose those lotus roots that have seven holes in the lotus roots.

And if we buy a common nine-hole on the market.

What about lotus root, then this kind of lotus root is more suitable for us to do some stir-frying, because the main thing is this, the taste of the nine holes is relatively crisp and tender, in the process of stir-frying, or in the process of cold dressing, it can achieve the best taste through the shortest time of cooking.

There are two reasons why black spots appear on lotus roots. One is that the lotus root is damaged during the growth period and the soil enters, so the lotus root can be eaten and washed clean. The second is that the lotus root contains phenolic substances, which will oxidize in the air, and the black part can be removed, so the lotus root can also be eaten.

It is normal for lotus root to have black spots after cooking. There is a kind of lotus root variety called seven-hole lotus, the appearance of seven-hole lotus root is relatively rough, often with a lot of brown spots, the color of the outer skin is often a piece of brown spots, the whole is brownish-yellow, after cooking, these brown spots will deepen, it looks like black spots, there is no hindrance to eat, you can taste normally.
