Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bonito (tuna)
- Provides the main protein and flavour, cooked gently in the potato broth.
- Potatoes
- Release starch as they cook, thickening the broth and giving the stew body.
- Tomatoes
- Add acidity and moisture, building the sauce base with the peppers and onion.
- Onion
- Adds sweetness and savoury depth as it softens into the base.
- Green pepper
- Contributes a fresh, slightly bitter aroma to the sofrito base.
- Oil
- Carries flavour and helps soften the vegetables evenly.
The step that matters
Adding the tuna and resting it. Tuna overcooks quickly and turns dry and tough. Adding it to the hot potatoes and letting it sit off the heat for a few minutes lets it cook gently through with residual heat.

Fit is the average pairing score against bonito, potato, onion, pepper, garlic, tomato, white wine. 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).
