Soaking squid with caustic soda takes a short time and grows fast, and the prepared squid is crisp, tender, clean and transparent with good brightness. The specific method is: put 500g squid into a basin, add clean water (warm water is available in winter), soak for 3-4 hours, then separate the head, whiskers and body of squid, replace it with clean water (excluding squid), add 40ml 50% 50% caustic soda solution, stir evenly, soak for 2-4 hours until the squid is sticky and shiny and can be picked up with nails. Then divide the files and soak them in clear water for later use.

Attention should be paid to foaming production: after adding lye, it should be stirred frequently to prevent uneven foaming and excessive expansion; Eat with the hair, and it should not be stored for a long time after hair; The squid after hair contains a lot of water, so the blanching time after cutting should not be too long, otherwise the texture will not be brittle.

Let's start with squid. There are generally two ways to make squid, one is called "oil wool" and the other is called "water wool". Introduce separately-

Squid with oily hair

Every 500g dried squid, mix with15g sesame oil and a little alkali in water, add squid and soak until soft. Then clean it up.

Squid by water method

First, soak dried squid in warm water for 3 hours. Take 5 parts of soda ash, 2 parts of lime and 45 parts of boiling water, pour them in, stir them evenly, then add cold water to stir them evenly, and filter them until the water cools down to become a 5% cooked alkali solution. Take out the soaked dried squid, soak it in the cooked lye for another 3 hours, and it will rise. After taking it out, rinse it repeatedly with cold water to remove the alkaline smell. Soak it in clear water and use it for cooking at any time. At this time, the fish swelled up, showing a bright flesh red and full of elasticity.

Key points of operation: the concentration of light yellow transparent tender squid alkali is low (more water), and the concentration of purple old squid alkali is high; Alkaline water should be light in hot days and strong in cold days. In the process of soaking hair, we should also pay attention to strengthening observation. Once the hair is swollen and the color is fresh and moist, it will be taken out immediately. Too long time will do harm to fish and affect the quality and taste of cooking.
