We love it too, Fennel. I poach it. It does pong a bit but I open doors and windows afterwards and spray the air with white vinegar. And I agree with tanith about the packaging.
Not that I’ve found Fennel although I’m very careful now and put the packaging straight into the outside bin and also rinse the plates straight away and scrape any leftovers into the outside food bin it seems to help with the smell.
We both like smoked haddock, but I don't like the smell when it's cooked. It seems to stink out the whole house for days. I usually cook it in the microwave covered with clingfilm for a few minutes. Is there any other way to cook it with less smell?
