People eat fish gravy a lot in Africa. Especially those living in Atlantic coastal countries.
Liberians eat it in the morning with boiled cassava, plantains, and eddoes. For dinner, it goes with rice and split peas, rice and kidney beans, checked rice, and more.
Here's what you'll need to make your fish gravy:
3 lbs fish
1 medium onion (thinly sliced)
2 tsps seasoned salt
1 tsp ground black pepper
1 C cooking oil
1 C flour
2 tsp tomato paste
2 1/2 C water
1/2 pod hot pepper (chopped, optional)
First you have to fry your fish:
Remove scales and clean fish (see tips below.) Hopefully, you can buy your fish already cleaned. Cut your fish into slices about 1 1/2 to 2 inches. Use a sharp knife to cut several slits in each piece of fish.
Add 1 tsp salt, 1/2 tsp black pepper, and 1 tsp seasoned salt. Mix to spread seasoning evenly. Add half of the chopped pepper (optional). Let stand for 30 minutes to allow seasonings to penetrate.
Coat fish on both sides with flour.
Add 3/4 cup of the cooking oil to a large skillet. Heat the oil on medium high. When the oil is hot, fry fish until both sides are brown. Reduce heat if your fish is cooking too fast.
Then you make your fish gravy:
Heat the remaining 1/4 cup of oil in a large skillet on medium high. Add 3 Tbs of flour to hot oil. Stir until well mixed.
Add sliced onions. Continue stirring until onions and flour are golden brown. Reduce heat to medium. Add tomato paste and mix in.
Add 2 1/2 C water. Add 1/2 tsp salt and 1 tsp seasoned salt, 1/4 tsp black pepper and rest of hot pepper. Stir.
Taste. Add more salt and seasoned salt if desired. Add fried fish to gravy.
Return to boil. Reduce heat to medium to low. Simmer until gravy has thickened as desired.
