Hi,
sorry about that. You reserve the 1/4 cup broth to mix the arrowroot in. You add the onions after you have simmered the cauliflower in th rest of the broth and the cream till the cauiflower is the consistency of cooked potato. Add the clams with the juice from the can after the onions are cooked to your liking. Heat the mixture again then add the reserved broth mixed with the arrowroot. Heat the mixture till it thickens but do not boil. In actuality you could probaly throw the whole lot in the pan and cook it and it would be fine. Just add the arrowroot mixed with cool liquid at the end then heat till thickened.
