Pumpkin Mulligatawny

Translated, mulligatawny means "pepper water," which is a pretty accurate description of this soup. But this time I wanted more body, so I threw in a can of pumpkin. The base recipe is: 1 yellow onion finely minced, 1 tsp each of ginger and galangal, 4 minced cloves garlic sauteed until soft in some olive oil and some butter. Add 1/4 cup of flour and continue cooking for a minute. Then add 1 tsp each of cumin, cayenne, and tumeric and sautee another minute. Add at least 4 cups of vegetable stock or water to desired thickness. Add 1 can of pumpkin puree and stir over medium heat until homogeneous.
