This is a delicious dish that is best when used with fresh fish, but canned mackerel will suffice. You can also substitute cod or salmon in this recipe. My wife loves the taste of the base of this recipe so much that she says you can substitute the fish with any meat for that matter. She has experimented beef, chicken and even tuna. She is in love with the flavor of this recipe, and I have to say, it is quite tasty! with This is not a complicated dish like many of recipes. The “run down” in the name of the recipe refers to how the fish is cooked in the coconut milk until it simply falls apart or ‘runs down’. It is a cross between a stew and a soup and with the coconut milk base and the flavors of the ingredients, this one is sure to please. We made our homemade coconut milk for this recipe and or you can used the canned kind. My wife also likes to use canned mackerel with the same ingredients below, 1 can of tomato paste, 1 green pepper and 1 cup of water to make a fish sauce of sorts. It taste good all the same. You can try this with green banana, sweet potato or whatever else you like…Check ‘dis one out mon! I’m telling you, it is GOOD!
