Red Lentil Soup with Lemon

I have been forever looking for the recipe of a tasty lentil soup that I had once in an Indian restaurant and never could find the recipe. It was called Mulligatawny soup but every recipe I've found looks nothing close to the one I ate. Then I found this recipe and it's hands-down one of my favorite soups of all time.

The recipe was printed in the New York Times: Red Lentil Soup with Lemon by Melissa Clark. I'm still on the look out for a recipe for the tomato and lentil Mulligatawny soup--if anyone has it, please, please, please share it with me. In the meantime, this red lentil soup keeps me pretty happy in the meantime, especially on chilly days.
