I love cooking fish in a batter or crumbed. I usually use flathead which is nice, but I would like to know what other fish works well when being cooked in a batter or crumbed?
When I fancy fish and chips I tend to use either cod or haddock and create a rich beer batter. Serve that with some home-made chips and you're set.
If I want something lighter, but still with a crust, I'd tend to go for mackerel. If that's not available, I'd be looking for seabass or snapper.
Cod is your classic batter fish, used in most Fish & Chips recipes. I've used Tilapia in batter before, it works great.
Tilapia is firm and extremely versatile in what you can do with it.
Tilapia works great when cut into inch long pieces: dip in egg batter, plain flour, fry....
I like to use Mahi, sometimes covered in crushed macadamia nuts. Served with some coconut rice and a mango salsa it's amazing.
Pangasius (or 'Panga') seems to be popular as well these days. It's firm enough to use for your purposes as well, typically aquacultured, and cheap.
