This dish is easy to make and takes next to no time to prepare. Please make sure to use prawns from sustainable sources. Marine Stewardship Council has lists of certified fisheries.
Melt the butter in a frying pan over medium-high heat. Once it's sizzling sautee the garlig for 30 seconds before adding the prawns, season with the curry and cayenne and paprika and cook until done. This is very quick, so don't take your eyes off them.
Remove the prawns from the pan and set aside.
Fry the leek and peppers until tender. Add tomato puree and cream. You may want to add a bit more seasoning according to taste.
Let simmer for five minutes then turn the heat off and add the cooked prawns.
Notes
The curry powder you buy in Sweden is slightly sweeter than those I have bought in other parts of the world. If you want that authentic Swedish taste, add a tsp of sugar.Serve with rice.
