There are several kinds of cold dishes, so when we want to use different kinds of vinegar, such as meat dishes, such as cold pig's ears, chicken, beef, etc., we can choose old vinegar with heavy taste, because meat dishes have heavy fragrance and are very suitable for this kind of vinegar. If it is a vegetarian dish, such as eggplant, Flammulina velutipes and cucumber, the best choice should be balsamic vinegar, which tastes more fragrant.
There is a little difference in taste between aged vinegar and fragrant vinegar. * * * Same as above, except acetic acid, fragrant vinegar is a little more fragrant than aged vinegar, and fragrant vinegar is also a little sweet.
