Since you want to make vegetarian soup and surpass the smell of broth, I think you should work hard at this time. The most important thing about soup is seasoning. All kinds of seasonings must be put evenly, not too salty or too sweet, which will affect the concentration of the soup. Then, don't put too much garlic, onion and ginger, just put a little, which will also make your soup more delicious. Then you can also put some flour in it. Playing in it will also increase the concentration of the soup, making it more delicious and smooth. My mother often puts some flour in the soup when she makes it. He said the soup would taste better. It is also important not to forget the last one.
When the soup is boiling, you can put some spinach, small vegetables or lettuce, which will look more appetizing as a whole. If you still feel that the taste is not good, you can finally put some sesame oil in the bowl, so that the whole soup will taste good.
