Warm to the Bone Lentil Soup

After a relatively warm early December, winter has finally hit Cambridge, and nothing says "winter" like a big pot of soup.  (Although, as I write this, a mild warm front is moving in, but I'm not complaining about that.)  

Multiple Christmas parties left me with three ham hocks, which got me thinking about lentil soup.  I bookmarked the Barefoot Contessa's recipe a while back, and as a fan of all things Ina, I was eager to try it (especially after an unsolicited ringing endorsement from a friend).  It becomes a vegetarian recipe if you swap out chicken broth for vegetable stock, has a classic vegetable backbone, and uses French green lentils, which I had in my pantry and wanted to use up.  But since I had so much ham and even more lentils in my pantry--red ones--I turned to Google for further inspiration.  This led me to a blogger's Red Lentil and Ham Soup with an Indian spice flavor profile.  Realizing I had all the necessary spices in my ridiculously stocked pantry I ambitiously, and perhaps foolishly, decided to do both.  (Honestly, how much soup can a single girl eat?)
