We all know that kelp is a relatively common food, it is eaten in a variety of ways, good flavor, high nutritional value, many people will often use kelp stew to eat. When buying kelp, many people will find kelp knotted. Then why will the kelp knot? Let's look at it specifically below!

What is the use of kelp knot Vegetable market

In the northern vegetable market to sell kelp buckle not many people, most of the people selling kelp is a large piece of kelp to make a big knot, so that consumers to sell home to toss to go, shredding, cutting, knotting are arbitrary. Food market in a large piece of kelp knot, because after drying kelp, it is easy to mess, so to give the kelp knot, this to storage and transportation are very convenient.

And the southern market is not the same, buying food is a delicate work, to exaggerate a little, in the south to buy cilantro can be bought one by one. And the southern food market to sell seaweed people, have the patience to make seaweed into seaweed buckle to sell. So in the south to sell kelp buckle is more common, but sell large pieces of kelp is not common, which is also a big difference between the north and south of the food market.

The kelp buckle in the market is finished, let's talk about the kelp buckle sold in the restaurant. Generally, only hot pot restaurant sells seaweed buckle, its important purpose is to facilitate diners to clip the seaweed buckle (hot pot oil, really not good to clip the piece of seaweed), the appearance is also good, the price of seaweed can be incidentally increased a little.

In fact, as long as the attention can be found, the same level of consumption of the two hot pot restaurant, selling seaweed buckle price than seaweed or seaweed pieces of the price is high. This is because there is another piece of the labor cost, the people in the back kitchen still have to cut the seaweed into small pieces, and then tie knots next to each other.

1: The main reason is that it is good for cooking, because the slices of kelp as soon as the pot, immediately stick to the pot, do not knot the kelp in the cooking, will stick to the bottom of the pot, resulting in paste, so the kelp should be knotted.

2: the surface of the kelp is relatively slippery, not good clip, knot to increase the friction with the chopsticks, after a knot will be very easy to clip the kelp up.

3: The surface of kelp will be slippery after boiling, it is difficult to separate it with chopsticks, and the kelp piled up together will also affect the taste.

4: Easy to preserve iodine.

5: After soaking the kelp should be dried, "hair" of the dried kelp is easy to break, a knot to facilitate transportation and storage.

6: There is also a saying that after the guests came to the knot it is the guests of the meaning of welcome and respect, but also looks more beautiful.

How to pick kelp is better

It's actually quite simple, you can start from the following four aspects:

Look at the color

The kelp that is served on the plate, it is green in color. However, the color of dried kelp is not green.

When we buy dried kelp, we have to pick the dark color of yellow-brown or green-brown kelp, which has not been chemically added, and when we soak it, it will have the green color that we commonly see.

Don't buy dried kelp if it's just green and brightly colored. There is a good chance that the kelp has been soaked in chemicals, hence the color.

Some dried kelp has a lot of white particles covering the surface, like a layer of white frost.

This white frost is neither dirty nor salt, it is actually mannitol produced by the weathering of plant alkali, which is rich in nutrients. If you see white frost on the surface of the kelp, it proves that it is a high-quality kelp.

Smell

Whether it is kelp or other seafood, their taste is similar, there is a kind of ocean salty fresh taste, and there is a faint fishy smell.

When picking kelp, smell the odor, if in addition to the normal odor mentioned above, you can smell other pungent odor, that these kelp is chemically added.

When shopping, don't just look at the surface of the kelp, it's best to turn it over carefully and check it out.

Some kelp looks bright on the surface, turn to the inside, but small and crumbly, there are a lot of empty holes, sediment, mold, so do not buy the kelp.

How to soak dry kelp

The soaking method of dry kelp: dry steaming.

Generally, when we soak dry food, it is directly placed in the water to soak. However, the soaking of kelp should never be done this way.

Because, kelp is also rich in brown alginate, alginate and other nutrients, these substances in the absorption of water, it will lead to a layer of viscous colloid on the surface of the kelp, which will prevent the further absorption of water, in which case, the kelp will be cooked impermeable to affect the taste. In addition, water-soluble vitamins, iodoacetic acid, mannitol and other nutrients in kelp are easily lost in water. Therefore, dry kelp is not suitable for soaking and soaking in water.

So, what should be done with the dry steaming and soaking of kelp? In fact, it is very simple. Steam the kelp in water for 30 minutes, and then wash it with water. Do a good job of kelp is very tender and delicious, eat crispy, whether cold or soup is very delicious!
