Ingredients: 30 kg flour, beef 10 kg.

Ingredients: 3 kg of beef liver, white radish 10 kg.

Seasoning: 7 taels of pepper, 0 taels of tsaoko 1 2, 5 taels of cinnamon, 0.5kg of ginger bark 1 2, 0.5kg of clear oil, 3 parts of monosodium glutamate, 3 taels of salt 1 kg, 3 taels of pepper, half a catty of fragrant lai, garlic sprout, chopped green onion and chili pepper oil.

method of work

1, wash beef and bones with clear water first, then soak them in water for four hours (the blood is reserved for another use), put them into a warm water pot, skim off the floating foam when they are about to open, add 4 taels of salt, 5 taels of Amomum tsao-ko, 5 taels of ginger peel and 2 taels of pepper, wrap them in gauze, wash them in clear water, then put them into the pot, simmer for five hours, and then cut them into pieces.

2. Cut the beef liver into small pieces and put it in another pot to cook and clarify it for later use. Stir-fry cassia seed, pepper, tsaoko and ginger bark with warm fire, dry and grind into powder, wash radish, cut into pieces and cook. Garlic seedlings, chopped green onion, and chopped shallots are reserved.

3. Skim off the oil slick from the broth, pour the blood soaked in meat into the boiled meat soup pot, and after boiling, skim the foam to clarify, add various seasoning powders, then pour a little water into the clear beef liver soup, boil it to remove the foam, and then add salt, pepper, monosodium glutamate, cooked radish slices and skimmed oil slick.

4. Add water 18 kg to 30 kg of flour, then knead it evenly, and pry and knead it evenly with 7 liang of grey water (less if the grey water is soluble, more if the grey water is weak). Wipe the oil on the case, rub the noodles into strips, pull them into strips weighing five taels, and cover them with wet strips of cloth. Then, according to everyone's hobby of eating well, they are pulled into noodles in the shapes of big width, leek leaves, two fine pieces, mustard wheat (triangular strips) and so on. After the noodles are cooked, they are fished into a bowl, and the beef soup, radish, diced meat and oil slick are poured into it. Add appropriate amount of fragrant lai, garlic sprout, chopped green onion and chili pepper oil according to everyone's taste.

Tips

The five steps of making Lanzhou beef Lamian Noodles noodles, including material selection, dough mixing, dough awakening, slivers and Lamian Noodles, skillfully use the physical properties of the ingredients, that is, the extensibility and elasticity of gluten protein.

First, select the surface

Generally, you should choose fresh high-gluten flour, and Lanzhou has beef Lamian Noodles special flour. It is not advisable to choose old flour, let alone contaminated flour which is moth-eaten, bitten by rats and mildewed, because this kind of flour not only does not meet the hygienic standard, but also contains protein molecules, which are decomposed into amino acids by protease (due to pollution and other reasons, the activity of protease is enhanced), so that protein can not combine with water to form gluten, thus greatly reducing the generation of gluten. Only fresh high gluten flour (special flour for Lanzhou beef and Lamian Noodles) with high protein content can guarantee the precondition for the success of making Lamian Noodles.

Second, dough mixing

Mixing dough is the basis and key of Lamian Noodles's production. The first thing we should pay attention to is the temperature of water, which generally requires warm water in winter and cold water in other seasons. Because the temperature of dough is easily influenced by natural air temperature, the temperature of the mixed dough is always kept at 30℃ by using different water temperatures, because at this time, the protein in flour has the highest water absorption, which can reach 150%, and at this time, the gluten production rate is also the highest, and the quality is the best, that is, the extensibility and elasticity are the best, which is the most suitable for stretching. If the temperature is lower than 30℃, the water absorption and quality of protein will decrease with the decrease of temperature. When the temperature exceeds 30℃, it will also reduce the generation of gluten. When the temperature reaches 60℃, it will cause the denaturation of protein and lose its properties. It is to keep the dough in the most suitable stretching range. Secondly, proper amount of water and ash should be put into the dough, because they can improve the production rate and quality of gluten in the dough. For example, an appropriate amount of water, its osmotic pressure can make the distance between protein molecules in the dough narrow and the density increase, especially make the viscosity of gliadin, one of the gluten protein, increase, thus improving the generation and quality of gluten. Pay attention to "three times of water, three times of ash, 9981 times of rubbing". The ash is actually alkali, but it is not ordinary alkali. It is an alkaline substance, commonly known as Peng ash, which is baked from the grass of the Gobi Desert. Adding it to the noodles not only makes the noodles have a special flavor, but also makes the noodles smooth, yellow and strong. In recent years, it has been replaced by special dough-mixing agent, and the dough-mixing skill is still the most important.

Third, wake up

Wake up, that is, put the mixed dough for a period of time (generally not less than 30 minutes in winter and a little shorter in summer), and its purpose is also to promote the generation of gluten. Placement can also make protein, which has not fully absorbed water, have sufficient water absorption time, so as to improve the generation and quality of gluten.

Fourth, the slip

After repeatedly pounding, kneading, stretching and throwing the dough, the young man with strong arm strength put the dough on the panel, held the two ends of the strip with both hands, lifted it up and slammed it on the chopping board. After the strip is stretched, the two ends are folded in half, and the two ends are kept being beaten, so that the purpose is to adjust the arrangement order of gluten protein in the dough, so that the disordered protein molecules are arranged in a long chain, which is called shun Jin in the industry. However, it is twisted into long strips, which are 20 mm thick and chopsticks long, or twisted into round strips.

V. Lamian Noodles

Put the slipped noodles on the chopping board, sprinkle with clear oil (to prevent noodles from sticking), and then pull out noodles with different sizes and thicknesses according to diners' hobbies. If you like round noodles, you can choose five styles: thick, two-thin, three-thin, thin and capillary. If you like flat noodles, you can choose three styles: big width, wide width and leek leaves; If you want to eat something angular, Master Lamian Noodles will pull a special bowl of buckwheat for you. Lamian Noodles has a unique skill. He holds both ends in his hand, and the two arms are evenly and forcefully pulled outward. Then the two ends are folded in half, and both ends are placed in the fingers of one hand at the same time (usually with his left hand). The middle finger of the other hand is hooked down to the other end, and the palm is turned up, so that the noodles form a noose shape, and both hands are pulled to both sides at the same time. After the noodles are stretched, put one end hooked by the right hand on the finger of the left hand, and continue to hook the other end with the right hand. When pulling, the speed should be fast and the force should be uniform, and so on, each folding is called a buckle. Pulling is a highly technical job, and it is difficult for beginners to master the essentials. The same dough, in the hands of experienced old chefs, not only has a fast Lamian Noodles speed (generally only takes about 10 second), but also the pulled noodles are uniform in thickness and do not break, which is difficult for beginners to do. A noodle joint just pulls a large bowl of noodles. Every time you pull it, you should fold it back on your wrist. When you pull it to the end, shake your hands up and down several times, and the noodles will be flexible and long, with even thickness. Generally, the thin one is 7 buttons, and the thin one is 9 buttons. The capillary surface can reach 1 1 button, and the strip is as thin as silk without breaking, which is really the essence of China cooking. Noodles are smooth and smooth, and can be fished out after a little boiling in the pot, which is flexible and non-sticky. There is a saying that goes down into the pot: "Lamian Noodles is like a coil of thread, which goes down into the pot and turns leisurely, catching chrysanthemum petals in the bowl". Watching Lamian Noodles seems to be an acrobatic performance.
