With very few exceptions, sweet potatoes are better than potatoes in my book. Not only do sweet potatoes nail the savory options, they also get to participate in the worlds of sweets and baked goods, a feat potatoes don't dare fathom. When presented with the option, I'll always choose the sweet potato option for fries, hashes or almost any other dish you can think of. And if presented with a potato soup or sweet potato soup, I'll choose the sweet potato option. Sweet potatoes can take on many flavors that potatoes can't, like the rich and creamy peanut butter that features so prominently in this soup. The sweet potato and peanut combination has a distinctly African feel to me, creating a heartiness than feels appropriate even in the warmer months. That deep comfort is contrasted perfectly by the spice of the chiles, brightness of the garlic and ginger, and freshness of the cilantro. I love these bold flavors in my food, but you may want to hold back on the chiles and cilantro for those with less adventurous palates or those you're slowly trying to introduce to a wider experience of flavor. Although unintentional on my part, this recipe has the added bonus of being both vegan and gluten-free, allowing you to accommodate adventurous eaters with all sorts of dietary restrictions (my apologies to those with peanut allergies) in fabulous fashion.
