Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Provide bulk and protein-rich body, soaking up seasoning and thickening the filling as they cook.
- Bell peppers
- Add sweetness and a tender-crisp texture that contrasts with the soft filling.
- Onions
- Soften and turn sweet as they cook, adding savory depth to the filling.
- Flour tortillas
- Hold the filling as a warm, pliable wrap that is folded for serving.
The step that matters
Reduce heat before thickening. Cooking the bean mixture gently after boiling lets the starch in the beans and the seasoning mix thicken slowly without scorching on the bottom of the skillet.

Fit is the average pairing score against pepper, beans, corn, parsley, flour. 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).
