Ingredients

Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Prepare the base

  1. Lightly fry the njansan for about 5 minutes.

  2. Set aside.

  3. Blend the onions, green onions, tomatoes, njansan, garlic, basil, and parsley together in a blender.

  4. Add some water to the blender to facilitate its blending to a purée.

Cook the stew

  1. Place a saucepan on the fire and heat it with a little oil.

  2. Add the blended mixture with very little water and bring it to a boil.

  3. Let it simmer for 10 minutes, stirring occasionally.

  4. Mix in the mbongo spice, fish, bouillon powder, and salt.

  5. Simmer for another 15 minutes or until the fish is fully cooked through.

  6. Add a little water if necessary to prevent the stew from getting burnt.

  7. Adjust the seasonings as desired.

Serve

  1. Enjoy warm with boiled plantains or any complementary dish of your choice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White fish or catfish
Provides the main protein, which cooks through in the simmering stew.
Njansan seeds
Adds a distinctive aromatic, slightly thickening character to the sauce when fried and blended.
Tomatoes
Add acidity and body to the blended base of the stew.
Garlic
Contributes pungent aroma that deepens as it cooks into the sauce.
Vegetable oil
Carries flavour and helps fry the njansan and start the sauce.

The step that matters

Adding water during the simmer. Blended onion and tomato sauces contain sugars and solids that scorch on the pan base, so a little water keeps the stew from catching and burning while it reduces.

Fit is the average pairing score against fish, onion, tomato, garlic, basil, chicken. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
