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

What each ingredient does

Onions
Browning in the hot oil builds sweetness and savoury depth for the dish.
Haricots verts (green beans)
Form the body of the dish, absorbing flavour from the onions and oil.
Oil
Carries heat to the onions and coats the beans, adding richness.
Vinegar
Adds acidity that brightens the buttery, savoury onions and beans.

The step that matters

Browning the onions. Onions need enough heat and time to take on colour; pale, under-browned onions give little sweetness, so the dish tastes flat. Stop once they just begin to brown to avoid bitterness from scorching.

Swap the green beans

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

  1. Carrotfits better
  2. Capsicumfits better
  3. Shallotfits better
  4. Green beansthe original

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