I don't really like cooking Tom Yum from scratch because its a very common dish, and whenever one gets the craving for Tom Yum, they want it here and now, rather than waiting hours for it! I followed your instruction (and the chinese supermarket near me sells kaffir lime leaves and galangal). It's made with shrimp, chicken stock, mushrooms, veggies, and spices. Classic tom yum soup with all the hot sour flavours you'd expect. You'll feel satisfied by all the crunchy, refreshing vegetables, and you could drink the broth alone by the mugful. To serve, pour the soup into two bowls and top up with the hot stock. Tom yum soup won't cure a cold but it will definitely soothe your body. Packed with herbs, spices and vegetables. Tom Yum is a thai hot and sour soup, as well as being spicy. Tom yum is really like a mix of different ingredients, all boiled together into a soup, and flavored with a trio of Thai herbs: lemongrass, galangal, and kaffir lime leaves.
