Question 10: Why do walnuts turn black when they are mature? Prepare crispy water and crispy paste There are many methods, but the principles are similar. There are two main types of seasonings. One is to use seasonings with heavy sugar content, such as maltose and fermented glutinous rice juice. These seasonings mainly play a coloring role during frying; the other is to use seasonings with heavy sugar content, such as maltose and glutinous rice juice. Use vinegar seasonings, such as white vinegar, balsamic vinegar, red vinegar, etc., to tighten the skin of the raw materials and facilitate even coloring during frying. Below, I will introduce a common method of preparing crispy water and crispy slurry. Method for making crispy water: First use 150 grams of boiling water to dissolve 200 grams of maltose, then stir evenly with 600 grams of white vinegar, 80 grams of red Zhejiang vinegar and 50 grams of Huadiao wine, and it is ready. You can also put the maltose into a stainless steel bucket, pour in white vinegar, red Zhejiang vinegar, Huadiao wine and water respectively, then heat it over low heat until the maltose dissolves, and stir well.

The preparation method of crispy pulp is similar to that of crispy water: first use 450 grams of boiling water to dissolve 300 grams of maltose, wait for it to cool, add 150 grams of red Zhejiang vinegar, 100 grams of Huadiao wine, and 150 grams of dry corn starch, and stir together to form a smooth paste. When it becomes a thin paste, it's ready. Crispy water and crispy slurry are suitable for making crispy pigeon, crispy chicken, crispy quail, crispy duck and other dishes. It should be said that the usage of crispy water and crispy slurry is similar, but when we make crispy dishes, we still need to pay attention to the following details. 1. Be sure to choose raw materials with undamaged outer skins. The internal organs of poultry raw materials should generally be removed from the anus, because this way the appearance can be kept as intact as possible. 2. The raw materials that are coated with crispy water will turn color quickly when fried, so the raw materials are usually cooked in advance using the white brine method, and then the crispy water is added. This will avoid the situation where the outside is colored but the inside is not yet cooked during frying. When marinating, it is best to make the raw materials just cooked, so as to avoid damage to the skin of the raw materials and tough meat. After the raw materials are marinated, use warm water to wash away the oil on the surface. If there is too much oil, the water on the skin will be uneven, which will easily lead to uneven color after frying. 3. The crispy water must be applied while it is hot. When applying the crispy water, you can also add an appropriate amount of food powder to the crispy water to make the outer skin of the dish crispier. After applying the skin water, use the barbecued pork ring to thread the raw materials and hang them in a ventilated place to dry the moisture. The drying time should not be less than 1 hour. If the ventilation conditions are not good, you can also use an electric fan to blow it. Once dried, the surface of the raw materials should no longer be stained with water, otherwise the water-stained areas will be difficult to color during frying. 4. The dried raw materials should be put into the pot for frying as soon as possible, or sealed with plastic wrap for later use. If the raw materials are blown too dry by the wind, the color will turn black before they are fried in the pot. 5. When frying crispy dishes, the oil temperature must be low when putting them in the pot. Sometimes you can even put the raw materials on a colander and drizzle oil to heat the inside of the raw materials. Finally, increase the oil temperature and fry until the skin of the raw materials is golden. Crispy. Ingredients for Sham Jing Crispy Goose: 1 black brown goose (weighing about 2.5 kg).
