In the process of pouring starch, it takes a long time to add water to dissolve starch in water. So you can't pour starch directly into the thicken. If water is added before the starch is poured, the starch will be better dissolved in water and the thickening effect will be better. So be sure to remember that starch can't be poured directly.
Preparation of water starch
Water starch is actually a mixture of water and starch, and we just need to master the ratio between them. The ratio of water to starch is generally controlled at 5: 1, and then it is good to stir evenly. One thing to note here is that the water used to prepare water starch must be boiled with cold water, not hot water, because hot water will make starch dough not completely dissolve in water.
In addition, according to our cooking, we can make appropriate adjustments. If it is soup, we can add less water. If the water is not dry enough, we need to add more water.
