This recipe makes a large quantity of soup. If you aren't serving a crowd, you can half the recipe or make the whole batch and freeze the soup. It's wonderful to pull out for an easy lunch at home or at work.
* If you're not familiar with coriander seed, it's actually the seed that cilantro is grown from. It tastes nothing like cilantro though. It has a citrusy flavor, often described as "warm, nutty, spicy, and orange-flavoured.1 ½ tablespoons sounds like a lot but it's not a strong taste, and along with the cilantro, is the main flavoring in this soup. You can find coriander, both whole and ground in the spice section of most any larger grocery store or online. I recommend the crushing the whole seed instead of using the ground as it's so much more flavorful.
** I love my immersion blender. It’s a real workhorse in my kitchen as I use it for all kinds of things. If you use a regular blender to puree any kind of soup, make sure to allow the soup to cool a bit before blending. This will prevent the heat from building up in the blender container and causing and explosion - not a pretty sight!
