The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Onions
Form the main body of the dish and soften to a tender, sweet texture when simmered.
Butter
Fat that carries heat for frying and gives the onions a light brown color and rich flavor.
Sugar
Adds sweetness and helps the onions brown and caramelize in the pan.
Glaze
Adds body and a glossy coating to the onions as the liquid reduces.
Stock
Liquid that simmers the onions until tender and forms the gravy.

The step that matters

Fry the onions in the butter until light brown. Browning develops flavor through the Maillard reaction and caramelization of sugars. Stopping too early leaves a pale, bland surface, while too much heat can scorch the butter and sugar before the onions are tender.

Swap the onion

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

  1. Capsicumfits better
  2. Potatofits better
  3. Sweet potatofits better
  4. Onionthe original

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