Cumin and fiery serrano chile infuse this simple soup as it cooks, and a dollop of sour cream provides a refreshing foil for the spicy flavors. For less heat, seed the chile first or use a milder pepper, such as jalape?
This is a fantastic recipe even for non-lentil eaters. The honey gives it a sweet taste and it is perfect served with rice. It's great as a main dish but could be a side as well.
