Cream of Cauliflower soup

I had this half cauliflower lying in my refrigerator for many days, waiting for its fate! And then I caught a bad cold. I wanted to eat something hot and delicious and soup, obviously, was my choice. This turned out to be a great soup and my cold was gone in no time (I am not saying there was any connection ;))
Anyway, here goes the recipe:

Ingredients:
1/2 cauliflower broken in florets
1 big onion chopped
1/3 bell pepper chopped (optional)
2 green chillies chopped (if you want hot soup)
5 garlic cloves, peeled
1 tsp cumin seeds
2 tbsp+1tsp clarified ghee or butter
1 tbsp all purpose flour
3 cup milk
3 tbsp whipping cream or fresh cream (optional for richer soup)
salt to taste
Black pepper to taste

In a big pan, heat 2 tbsp ghee. Once ghee is hot add cumin seeds. When seeds crackle, add garlic and green chillies. When garlic turns golden brown, add onion and little bit salt. Saute for a minute and then add bell pepper and cauliflower. Let it cook on medium with pan covered until the cauliflower florets are semi-soft. Turn off the stove and let this mixture cool a bit. Now grind this mixture in a grinder. In another pan on medium heat, add 1 tsp clarified ghee. When ghee is hot, add all purpose flour. Saute it and very quickly add milk and grinded paste of cauliflower. When the mixture comes to a boil, add the cream. Let it cook until the desired consistency of the soup is reached. Adjust salt and pepper and serve hot. You can serve with a thin stripe of bell pepper or a dash of cream.
