What to do with curdled cauliflower cheese?

[Movinghouseatlast]

I made a big cauliflower cheese yesterday, with the aim of freezing half. It bloody curdled in the oven.

I don't want to waste it. I was thinking of soup. If I whiz it up would it kind of hide the curdle? Then I could add stock?

Thanks.

I frequently make soup from leftover cauli cheese, blitzing will sort it.
