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

What each ingredient does

Seitan
Provides a chewy, meaty texture, and browns in the pan for savory flavor.
Onions
Soften and caramelize as they cook, adding sweetness and depth to the filling.
Red bell peppers
Soften during simmering, adding sweetness and body to the filling.
Avocado
Adds creaminess and fat, giving the sauce a smooth, rich texture.
Nonfat plain yogurt
Adds tang and creaminess to the sauce, balancing the richness of the avocado.
Lime juice
Adds acidity that brightens the sauce and balances the richness of the avocado and yogurt.

The step that matters

Browning the seitan in a dry-ish nonstick pan. Seitan needs enough direct contact and steady medium heat to brown; crowding or stirring too early steams it instead, leaving it pale and less flavorful.

Flavor stand-ins for the jalapeno

How well each one fits the dish's main ingredients (avocado, yogurt, pepper, lime, wheat, oregano, olive):

  1. Corianderbetter flavor fit
  2. Cuminbetter flavor fit
  3. Basilbetter flavor fit
  4. Jalapenothe original

Fit is the average pairing score against avocado, yogurt, pepper, lime, wheat, oregano, olive. 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).
