Some arctic sweet shrimps have dark heads, showing brown and black, commonly known as "blackheads". Some consumers mistakenly believe that this is a problem with the quality of arctic sweet shrimps. In fact, blackheads are a normal phenomenon.
Arctic sweet shrimp grows in the sea below 200 meters, and feeds on zooplankton and seaweed in the deep sea. These deep-sea zooplankton or seaweed are brown or black because they don't see sunlight all year round. The stomach of Arctic sweet shrimp is not in the abdomen like the general marine fish, but in its head, and its head (that is, the stomach) naturally presents a faint brown or black color, especially when it is full.
Arctic sweet shrimp is directly caught from the deep sea by large trawl. The Arctic sweet shrimp is directly dragged onto the boat from the deep sea of 200-300 meters. Sometimes, due to the rapid trawling speed and the rapid change of atmospheric pressure, the head (stomach) of the shrimp is easy to break, and the zooplankton in it also spreads. In this way, the faint black stomach contents (zooplankton) appear.
Blackheads are actually zooplankton and seaweed in the deep sea, because they also grow in the pure and pollution-free Arctic and North Atlantic deep sea, so they are as harmless as Arctic sweet shrimp. Ryan food tip: people who like it can safely eat it with blackheads. If they don't like it, they can just throw away the shrimp head, but there is no need to worry about the quality of Arctic sweet shrimp. It is precisely because of the existence of some blackheads that the Arctic sweet shrimp is a real wild shrimp.

If there are old people and children at home or people with sensitive stomach and intestines who eat sweet shrimp, it is safest to rinse it with warm water at least a few times, or blanch it in boiling water for a short time. Don't cook the red shrimp for too long, otherwise it will affect the taste. In addition, after adding the green garlic sprouts or leeks, stir-fry them quickly on high fire for two times, then turn off the heat and put them on the plate. This dish can be finished in about 1-2 minutes from stir-frying to dish loading. It is very simple and easy to use.
