Alkaline hair method is often used to swell dried squid. Alkaline hair method is to soak dry materials in cold water first, and then soak them in alkaline water to make them rise and return to softness. Alkaline hair can make hard raw materials soft and tender, such as dry raw materials such as squid and cuttlefish. This method uses the corrosion and degreasing properties of alkali to promote the dry material to absorb water and shorten the swelling time, but it will also cause some losses to the nutritional components of raw materials.
Alkali hair can be divided into two types: raw alkali hair and cooked alkali hair. The specific method can be decided according to the situation of raw materials and cooking needs.
The preparation of raw soda water is to put 0.5 kg of soda ash into 10 kg of warm water, and then dissolve it into 5% soda ash solution. The raw materials soaked in raw alkali have a greasy feeling, and the swelled raw materials have the characteristics of softness, tenderness and good taste, and are suitable for burning, stewing, mixing, stir-frying and soup dishes.
The preparation of cooked alkali solution is to put 0.5 kg of soda ash and 0 0. 15 kg of quicklime into a pottery vessel, add 5 kg of boiling water and stir evenly, then add 2.5 kg of cold water and stir evenly. After standing for clarification, take the clarified alkali solution for use. The raw materials soaked in cooked alkali are not sticky and slippery, and the swelled raw materials have the characteristics of toughness and tenderness, which are suitable for frying, frying and frying.
Swelling dried squid with raw alkali water: soak dried squid in cold water for about 3 hours (to soften the squid), then cut it into pieces with uniform size, soak it in raw alkali water for 5-6 hours, then pour boiling water, cover it and stew it, after cooling, pour it into an iron pan together with alkali liquor, slowly heat it with low fire, and upgrade the quality at a constant temperature of 80℃ ~ 90℃ (while adding clean water to the pot, Finally, fish out the full-grown squid slices, put them in a clean water basin, constantly change the water for bleaching, and remove the alkaline smell. When the squid slices become thick and elastic, they can be soaked in a solution with a little alkalinity for storage.
Swelling and drying squid with cooked alkaline water: put the squid slices soaked and softened and changed into cooked alkaline water, soak them until they are swollen and fully developed, then take them out, soak them in clean water and constantly change water to remove the alkali, and finally soak them in a solution with trace alkalinity and store them for later use.
Pay attention to the following points when using alkaline water to swell and dry squid:
1.The concentration of alkali solution should be adjusted appropriately according to the tenderness of dried squid and the cold and hot climate. For example, if the dried squid is big and hard, the concentration should be slightly larger, and if it is small and soft, the concentration should be small; In summer, the concentration should be small, and in winter, the concentration is slightly larger.
2. The rising time is closely related to the concentration of alkali solution. When the concentration is high, the swelling time can be shortened, and when the concentration is low, the time can be appropriately extended.
3. The dried squid can be soaked and softened, and then put into alkaline water to swell, which can reduce the corrosive effect of alkaline water on squid. However, changing squid into slices with uniform size can make squid swell and develop in the same degree.
4. When the hair rises, the first hair should be fished out first, and the hair that has not been sent out should continue to be sent, so as to avoid some excessive hair growth and some insufficient hair growth.
5. When upgrading with raw alkali water, it must be carried out in a constant temperature solution of 80℃ ~ 90℃. If the alkali liquor boils (100℃), it is easy to melt squid meat. In practice, the pot can be removed from the fire or cold water can be added to maintain a constant temperature. However, when the hair is swollen with cooked alkaline water, heating is not needed.

Dried squid with soaked hair
(1) Oiling: Use sesame oil10g for every 500g of dried squid, with a little alkali, and put it in water at the same time until it is soft.
(2) Alkali development: mix soda ash with cold water according to the ratio of 1:2, and after stirring, get 5% soda ash solution, and then add 20% to 30% depending on the tender squid.
Soak the dried squid in cold water for 3 hours, then take it out, put it in soda ash and soak it for 3 hours, and then it will swell up. Take it out and rinse it repeatedly in cold water to remove the alkaline smell, and then cook it.
