Creamy Cauliflower Soup with Turmeric

I love what cauliflower does to a soup - it's much more than you might think, if you imagine cauliflower as a Limp Steamed Vegetable! And turmeric supposedly does all sorts of good things for conditions like Dementia, etc...except I can't remember what it does, exactly...

At least this is delicious. :)

3 T. ghee
1 lg. onion
2 lg. heads cauliflower (~8 cups florets)
3 lg. cloves garlic, sliced
1 T. tomato paste
1 T. plus 2 tsp. turmeric
2 tsp. mustard powder
1 bay leaf
6 c. chicken stock
1/2 c. heavy cream
3 T. fresh dill
salt and pepper, to taste

Saute onion and 5 c. cauliflower, till beginning to soften. Add garlic, and saute for a few moments, until fragrent.

Add tomato paste and spices, stirring constantly for 1-3 minutes (don't burn!).

Add broth, and bring to a boil; cook till the cauliflower is soft. Remove the bay leaf; blend till smooth.

Add the bay leaf back in, plus the remaining cauliflower florets; simmer until the chunks of cauliflower are tender.

Stir in cream and fresh dill, and serve.
