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

What each ingredient does

Green tomatoes
Provide the main bulk and a tart, firm bite that holds its shape when fried.
Onion
Adds sweetness as it softens and browns, balancing the tart tomatoes.
Drippings
Supply fat for frying and carry flavour into the vegetables while helping them brown.

The step that matters

Frying until golden brown. Stirring only occasionally lets the vegetables sit against the hot pan, which is what creates browning. Moving them too often steams them instead, leaving them pale and soft.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper):

  1. Capsicumfits better
  2. Eggplantfits better
  3. Carrotfits better
  4. Onionthe original

Fit is the average pairing score against tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
