Heat a grill pan on medium-high heat. Brush some canola oil on the ears of corn. Grill the corn for a few seconds on all sides until marked. Slice off the corn niblets. Add the corn, wild rice, and cooked black beans to the soup. Season the soup with brown sugar, sea salt, freshly ground pepper and coriander (cilantro) to taste.
Serve this soup with a dollop of creme fraiche, crispy tortillas and a squirt of fresh lime juice.
Cut the organic chicken and chicken bones into pieces. Really hack into it so that the bones and marrow are exposed. Add the chicken pieces and pint of chicken bones to the pot. Fill the pot with water until it just covers all the chicken, and bring to a boil.
Once the broth has begun to boil, bring the heat down to medium-low. Partially cover, and let the broth simmer for 2 to 3 hours.
Refrigerate the broth overnight. Slip a sharp knife around the edges of solidified chicken fat and discard.
