Chapter 626: Is the Sea Fish Salty? {Ask for a commuter pass}

The crispy golden flesh of the fish is easily separated by the chopsticks, and the crispy skin of the fish can be clearly felt through the touch transmitted by the chopsticks.

Tearing open this crispy skin, you can feel the softness of the fish, the fat flowing between the fish and the skin, and the fragrance is stimulated by the high temperature, which makes the hungry duo's index fingers move and start with the sea breeze.

Cut off the head of the barracuda and continue frying, Bi Fang took a bite of the fish, and the umami was stimulated between his lips and teeth.

The sea shuttle does not have as many spines as the river shuttle, and Bi Fang is not afraid of the card owner, so he directly smacked off most of the one, and then licked his oily lips.

"Barracuda has rich nutrients, the meat is tender, delicious, the protein content is very high, it is a delicacy on the high-end banquet, especially the spring Kailing shuttle is the most precious, although it is September, not the fattest season of the barracuda, but it is still delicious."

Eat the whole barracuda, there is still a barracuda head, not thrown away, after the roast is slightly black, Bi Fang sandwiched it and eats it with the bones and meat, crispy and at the same time with the lubrication of the fish brain, the layers are richer, and Bao Waisi looks constipated.

"Can you eat fish heads?"

"Give it a try." Bi Fang didn't say it directly, just asked Bao Weisi to try it.

After hesitating for a moment, Bauwaisi, who had lost a whole barracuda, turned the fish bone upside down, and pointed the head of the fish at himself, with his big eyes facing his small eyes.

It's not that you don't eat fish heads, just look up at the starry sky, and you can see that all fish heads are facing the sky.

But Bauwaisi himself didn't like it, but because of Bi Fang's kind invitation, he still cautiously opened his mouth and bit half of it.

As soon as he entered, Bauwais's eyes lit up.

The fish head on the outside has become crispy like potato chips after a long time of grilling, which is very different from the backbone and is more fragrant.

Finally, you can feel the burst of fish brains, with a strong salty flavor.

Seeing that Bao Waisi enjoyed it very much, Bi Fang smiled with satisfaction: "The cooked barracuda is fragrant with the head, and there has always been a saying among the people that 'if you lose the car and the cow, you don't lose the head of the barracuda'." ”

The fish brain inside the fish head is roughly a transparent gelatinous liquid shape, and when cooked, it will have a very fragrant taste of bone marrow collagen, which is very delicious and delicious, and can be called the best delicious part of the fish head.

"And it contains a small part of seawater, so the saltiness is very obvious, although the fish itself is fragrant, but there is no saltiness, and it tastes relatively bland."

[Hey, shouldn't saltwater fish be saltier?] 】

[The saltwater fish itself is salty, and some methods do not need to put salt at all, and they have a salty taste (smile)]

【。。。 Are saltwater fish pickled? 】

Bi Fang shook his head: "First of all, I have to admit that the salt concentration of body fluids of marine fish is higher than that of freshwater fish, but this difference is not very big in bony fish, so it is still necessary to add exogenous salt when cooking fish." ”

The audience moved out of the small bench and pricked up their ears.

"The salt concentration of body fluids in marine bony fish is lower than that of external seawater, and they regulate their osmotic pressure independently."

"There are two main ways for marine bony fish to regulate osmotic pressure, one is to drink more water, in addition to the water in the diet, marine bony fish will drink a lot of water directly."

"On the other hand, there are special salt-secreting cells on the gills of marine bony fish, and after swallowing seawater infiltrates into the bloodstream in the intestines, the water will be retained, and the excess salt will be excreted from the salt-secreting cells on the gills, and some other salts will be excreted from the urine, but the renal bodies of marine bony fish are very degenerated and the urine output is very small."

Bi Fang explained as he gestured his hand to his neck, as if there were also gills growing there.

"The salt cells on the gills are the main way for marine bony fish to excrete salt, mainly sodium chloride, and other divalent ions such as calcium, magnesium and sulfate are excreted in the urine.

"This ensures a low osmolarity environment in marine bony fishes. Therefore, it is still necessary to add salt when cooking marine bony fish. ”

The audience was stunned.

Because of this, marine fish and river fish are actually similar, and without salt, they have no taste.

Bauwaisi also listened very carefully.

I have to admit that the charm of being able to answer any question is really quite powerful.

This kind of erudition in the wilderness gives people a strong sense of security, and when you don't know whether the creature in front of you is poisonous or dangerous, he can easily give an accurate answer, so that you have a lot less worry and fear.

"Cartilaginous fish are an exception." Bi Fang added again, and then the audience saw that Bi Fang seemed to have thought of something, and a disgusted expression appeared on his face.

Cartilaginous fish ...... Typical is sharks.

That taste......

Bi Fang remembered the whitetip shark he ate at the beginning, and there was a strong smell of urine on the shark's meat, which is how cartilaginous fish regulate osmotic pressure, through the concentration of urea in the blood.

"The osmotic pressure of marine cartilaginous fishes is a completely different form, and the osmotic pressure of marine cartilaginous fishes is higher than that of marine cartilaginous fishes, and sometimes even higher than that of seawater."

"They regulate osmotic pressure through changes in the concentration of urea in the blood, and when the amount of urea in the blood is high, the water intake increases, the concentration of urea in the blood is diluted, urination increases, and urea decreases."

"When urea levels are reduced to a certain level, water intake decreases, urination decreases, and urea concentrations increase. Cycle. ”

"Because of this strange way, if you really want to eat it, you have to add a lot of salt to suppress the strange taste of cartilaginous fish."

[Strange knowledge increased]

[So shark meat is salty, is it (dog head)]

[Not only salty, but also sassy (funny)]

At the same time, the crabs stewed in clear water were also well, red, and seemed to be quite large because no one came to eat them, and their bodies alone were the size of a palm.

It was indeed delicious, Bi Fang opened the back shell of a crab, and the crab roe inside was quite full.

The two of them ate six fish in a row, plus six crabs, before they stopped.

Bi Fang ate relatively cleanly, and Bao Waisi ate crabs a little bit, and the people who watched it were heartbroken.

After burping, Bao Weisi touched his stomach and exclaimed: "Although there are not too many condiments, this is still a very unforgettable meal in my life, looking at the sea, the wind, and the endless wilderness, which makes me feel that I have tasted the most primitive natural taste." ”

After eating and drinking, Bi Fang only took a short rest before looking up at the weather.

In September, it was dark and it was late in the evening, and it was until 9 o'clock in the evening.

It's only four o'clock, and they still have a lot of time.

"Our cave still needs to be repaired, with a roof and a wooden door that gives us a sense of security."
