What's for Dinner?

[Sundae]

I love butter chicken.
It sounds so innocent...

Am looking into making a rich fish stew.
Dads won't appreciate it, but I know Mum will.
Trouble is, fish does not need to be cooked for a long time (unlike cheaper cuts of meat) so the broth doesn't seem to thicken.
The photos of promising sounding recipes look like a pile of tumbled seafood in coloured water.

I'd like a tomato-y base (but not too rich as Mum has problems with that).
Am I thinking of a Tuscan dish? Or a Spanish one?
I can't even cheat and buy a jar of something as they are all for meat. And after the meatloaf I have a horror if making another over-seasoned dish

Sorry, thinking out loud here. But if anyone can think of a lovely fresh tasting tomato based fish dish with fruits de mer and a little firm white fish, do share!
