Hi Chris
I haven't tried it with the grated carrot, I just used the original recipe (first post).
Oh and I didn't have Fennel seeds, so I added about a quarter tsp of cumin seeds, and I now add a couple of those Indian Bay leaves too.

I have frozen some, but haven't tried it yet, so can't really help there.
Can't see it being soggy though, as after it has been in the oven for a while it becomes quite dryish and nicely separated (as it is in the restaurants here).
