Although I liked the look of this recipe I wasn’t sure about adding soy sauce so decided to read some of the reviews and was so glad I did. I took the advice from a few of them by omitting the soy sauce and adding chorizo, black olives, chilli, garlic and used basil instead of thyme. The results were amazing so thank you to all of you for your very valid comments. My friend then made it using fresh basil and thyme adding smoked paprika and a little more chilli than I did. The results were even better! Such an easy dish to make with restaurant like results!

After reading the comments I did leave out the soy sauce, I added capers, a little chorizo, a couple of garlic cloves and used sea bream as the shop didn't have cod. It was really delicious and I would definitely make again. Added a sprinkle of cayenne pepper to give it a little kick. Easy to prepare and cook, the fish was lovely.

I love this recipe but I add some garlic and a tin of butter beans and flake the fish to serve as a stew rather than with potatoes etc on the side. I also use dried thyme and just as good

Wow, this dish was amazing!!! I was afraid it might be bland, but I used harissa paste in the tomato sauce, as well as garlic and capers and the sauce was delicious and spicy (thanks to the harissa) and not bland at all. I also used fresh basil in addition to thyme and fresh tomatoes as they needed to be used. The cod was very juicy and not dry at all, which often happens to me when I fry cod. Will definitely make this again, a super easy, quick and healthy mid-week dinner. I did not use soy sauce, I don't think it needs it and it also doesn't fit in my opinion. But if you like capers, I totally recommend using them.

Wow!! I just made this and it was amazing. I was a bit worried that it might be bland, but it wasn't. I added harissa paste to the sauce as well as capers and garlic and it was very spicy and delicious. Will definitely be making this again. The fish was super moist, which was amazing, since cod can get quite dry when fried, but here it just simmered in the juicy sauce and it was a perfect, quick and healthy mid-week meal. BTW, I used fresh tomatoes that needed to be used up and it worked very well. I also added fresh basil in the end, but no soy sauce. highly recommended dish.

This recipe has become a regular in our house. As other comments suggest, it's better without the soy sauce in my opinion. I have made this with the addition of chillies and replaced the thyme with fresh coriander. It has cooked beautifully every time!

added a chopped green jalepeno to the base sauce - adds extra depth of flavour and a slight heat kick

This is a great base recipe . As per other comments I gave up on the soy sauce and I added some garlic, chillies, chorizo, tomato paste, a splah of white wine and increased the amount of thyme. Served with baked baby potatoes , it came out delicious .

I used 1 tsp of soya sauce instead of 1 tablespoon, added more thyme and a tsp of mixed herbs, plus 2 cloves of garlic. Absolutely delicious.
