Chili Spiced Sweet Potato Soup

On a heartsick night, this soup seems a perfect antidote to my memories of meals eaten with old lovers. Not only is it ridiculously easy - helpful when your confidence (kitchen or otherwise) is low - but aside from roasting the yams, you don't really have to cook it. And, I offer my humble disclaimer that it doesn't actually contain proper sweet potatoes... but chili spiced yam soup just doesn't sound as sexy.

Here's what you need to make enough for two, or for one tonight and one tomorrow:
3 medium sized yams (i like garnet or jewel)
2 cups veggie stock, simmering
1/4 tsp cumin, or to taste
1/4 tsp chipotle, or to taste
1/2 tsp chili powder, plus extra for garnish
1 tsp fat (i used leftover bacon grease, but you can use butter or oil)
sour cream, for garnish

Here's what you do with it:
preheat oven for 10 min to 350 degrees.
roast yams in their skins about 45 minutes, until soft and sugars are dripping like caramel
a few minutes before yams finish, heat stock to boil and then keep hot over low flame
remove the yam peels, carefully, and eat or feed to your veggie loving dog
place peeled yams and hot stock in blender, or if you're fancy in a pot and use your immersion blender in the pot
add spices, fat and blend until smooth and silky
top off with a dollop of sour cream, chili powder and enjoy each ever-loving spoonful.

here's a shot of the remnants... the kitchen stove light doesn't do a whole lot to show off the color blast happening in the bowl.
