Sweet Potato Soup
Why This Recipe Works
Most sweet potato soup recipes call for so many other ingredients that the sweet potato flavor is muted. By cutting back to just shallot, thyme, and butter and using water instead of broth, we put the focus back on the main ingredient. We also puree some of the potato skins into the soup for extra earthiness. However, the real key to intensifying the sweet potato flavor was using only a minimal amount of flavor-diluting water. To do so, we let the sweet potatoes sit in hot water off heat for 20 minutes to make use of an enzyme that reduces their starch content. Less starch meant we could create a soup with less water, keeping the sweet potato flavor in the forefront.
