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

What each ingredient does

Chickpeas
Provide firm, hearty body and bulk to the filling so it holds up inside the taco shell.
Black beans
Add soft, creamy texture and bulk that thickens the filling as it simmers.
Pinto beans
Add soft, mealy texture and bulk that helps the filling become thick.
Tomato sauce
Adds moisture and acidity that combine with the beans into a thick, cohesive filling.
Cheddar cheese
Melts over the warm filling, adding fat, salt and savory richness.

The step that matters

Simmer until thick. Simmering reduces the moisture from the tomato sauce and bean liquid. If the filling is too wet it will soak the taco shells and turn them soggy, so cook until it is visibly thick before filling.

Flavor stand-ins for the onion

Fit is the average pairing score against olive, pepper, oregano, cumin, garlic, chickpea, beans. 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).
