The secret for a GREAT Red Thai fish curry is, of course, a really good-quality red curry paste, and the best fish you can find out there.

If you live in a big city like London, you know how difficult it is to source high-quality fresh fish and seafood.

And when you do find it, prices can be pretty high, and by high I mean really really high.

This award-winning company ethically sources the freshest possible fish from the daily fish markets on the Cornish bay area.

They make sure you get the best, the most seasonal and sustainable products.

The fish is then fully prepared to your own requirements and delivered to your door within 24h, carefully packed to keep all its freshness.mussels and fish fillets on wood board with parsley and lemon, plate with scallops on white cloth on the side I picked the Cornish Seafood Selection box, which included all sorts of seafood goodness: fresh scallops, mussels, hake fillets, trout fillets and plaice fillets.

The amount of fish & seafood you receive in your box is usually enough to feed a family of four.

Ingredients For Thai Red Fish Curry

When it comes to this fish-loaded Thai red curry, versatility is one of the things I love more about.

You can use pretty much any fish fillet and seafood you have at hand. For my fish curry, I used:

  • mussels
  • scallops
  • trout fillets
  • hake fillets

Same goes for the vegetables, you can use anything you like really. I used:

  • bell pepper
  • snow peas
  • pak choi
  • white onion
  • carrot

Together with the fish and veggies, you will need to add some Thai curry staples of course.

I use the following ingredients to bring my curry to life: Thai red curry paste, coconut milk, lemongrass, coriander and lime. You can also add some fresh kaffir lime leaves if you have them on hand.

Difference between Thai Red Curry and Thai Green Curry

The red curry is the absolute star of this dish, obviously.

Many of view ask me regularly which curry is best to use when it comes to Thai curry.

The main differences between Thai red and green curry paste is that the color and the chillies used.

Red curry is made from dried red chillies. Green curry instead, gets its signature colour from fresh green chillies, to enhance the flavour, basil, coriander and lime leaves are also added.

Red curry is less spicy than the green curry, so it’s the best choice if you don’t like super spicy stuff.

This recipe calls for red curry paste, but you can totally use green curry paste if you like.

For the curry paste, you can, of course, make your own, as I often do.

If you’re in a hurry, just buy a good quality Thai red curry paste from your local Asian store, or from the international aisle of a big supermarket.

Once you have all your ingredients at hand, this Thai Red Fish Curry comes together very easily and all in one pot.

You may follow the traditional route and use a wok, or opt for a cast-iron skillet or a regular frying pan.Thai Red Fish Curry in cast iron skillet, next to fresh cilantro, red chili peppers and halved limes, a small bowl with rice and black chopsticks.
