Why it works: Butter and fish match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 4,432 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: wheat, peanut, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: couscous
Directions
Make the sauce
Heat the vegetable oil in a large pot over medium heat.
Add the onions and garlic to the pot and sauté until they become translucent.
Stir in the diced tomatoes and tomato paste, cooking for a few minutes until the tomatoes soften.
Add the peanut butter, ground paprika, cayenne pepper, salt, and pepper to the pot. Stir well to combine all the ingredients.
Slowly pour in the water while continuously stirring the mixture to ensure the peanut butter is well incorporated.
Bring the sauce to a simmer and let it cook for about 15–20 minutes, allowing the flavors to meld together.
Cook the fish
Gently place the bonga fish fillets into the simmering sauce, making sure they are fully submerged. Cook for another 10–15 minutes or until the fish is fully cooked and flakes easily.
Taste the sauce and adjust the seasoning if needed.
Serve
Remove the pot from heat and let it cool slightly before serving.
Garnish with freshly chopped parsley or cilantro.
Serve the bonga fish domoda hot with rice or couscous.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanut butter
- Forms the thick, rich body of the sauce and adds nutty flavor and creaminess.
- Tomato paste
- Adds concentrated tomato flavor, depth, and a little acidity to the sauce.
- Onions
- Build the sweet, savory base of the sauce as they soften and turn translucent.
- Tomatoes
- Contribute moisture, acidity, and body as they soften into the sauce.
- Bonga fish fillets
- Provide the main protein, which firms and flakes as it cooks in the sauce.
The step that matters
Simmering the fish in the sauce. Once the fish is added, the sauce should simmer gently rather than boil hard, because vigorous boiling can break the fillets apart. Peanut sauce can also scorch on the bottom of the pot if not stirred, so the fish should be fully submerged and cooked until it flakes easily.

Fit is the average pairing score against onion, garlic, tomato, butter, pepper, fish, parsley. 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).
