Good point Jeera,
If in doubt, fish 'em out!

I reckon it would be a good idea to fish out any cassia bark or cinnamon sticks.
But, as I said, if the whole spices are otherwise soft enough to blend fine enough, I think they are ok to be left in. I have just made Andy's curry base. I left all of the whole spices in and they were soft enough to be blended into indiscernible oblivion! Just to recap, this included:
- 10 cardamom pods
- 2 tsp fennel seeds
- 1 tsp cloves
- 1 tsp ajwain seeds
But I think I'm right in saying that CP and Andy advocate leaving them all in (rightly or wrongly)?
Regards,
