The above is the cooking method of cooking sauce or base sauce that I know. Of course, if it is too troublesome for foodies, or Kitchen conditions are limited, you can directly buy finished yellow juice powder, but you must filter it before use, otherwise due to uneven mixing, there will be a large number of particles in the prepared yellow juice, which will greatly reduce your sauce.
