There is just something about the intense citrusy tartness and flavors of lemongrass, fresh lime, spicy chiles, and colorful veggies that I adore.

The first time I tried tom yum soup was at a small Thai restaurant in North Hollywood. I had ordered won ton soup and my husband decided to try something new, which of course, I had to sample. Let’s just say, his tom yum won over my won ton. We were both hooked, immediately.
As soon as we got back home, he went on a quest to make his own tom yum soup. The challenge was, many of the key ingredients weren’t items we kept on hand. In fact, some we hadn’t ever heard of, like kaffir lime or galangal. After doing a bit of research, he visited a local Asian market and found the ingredients he needed. A couple hours later, we had a big pot of the best vegan tom yum soup!

What is Tom Yum Soup?
According to Wikipedia, tom yum or tom yam is a type of hot and sour Thai soup, usually cooked with shrimp (prawn). Tom yum has its origin in Thailand.
The words “tom yam” are derived from two Thai words. Tom refers to the boiling process, while yam refers to a Thai spicy and sour salad. Tom yum is characterised by its distinct hot and sour flavours, with fragrant spices and herbs generously used in the broth. The soup is also made with fresh ingredients such as lemongrass, kaffir lime leaves, galangal, lime juice, fish sauce, and crushed red chili peppers.

With our vegan tom yum soup recipe, we omitted all the animal-derived ingredients. It’s so much better for us, the animals and the planet!
