Add one teaspoon chilli powder and some salt to the prawns and marinate for 30 minutes
Heat oil in a large saucepan and fry prawns, about a minute on each side. Remove from oil and set aside
In the same pan add the onion, thyme and celery
Sauté until onion is translucent
Add the garlic and fry for a minute
Add the other teaspoon of chilli powder and fry for a few seconds
Add the potatoes and carrots and sauté for 5 minutes. Add water and bring to the boil. Cover and simmer until carrots and potatoes are tender
You can remove the bay leaf and use a stick blender and give it a quick blitz. It doesn't have to be smooth
Return to the heat and add the fish. Cook for about 2 minutes, just until the fish turns white. Add the prawns and turn the heat off. The fish will finish cooking with the heat from the stew.
Garnish with parsley and add a drizzle of lemon juice. Serve with crusty bread
