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

Eggs
Set the custard around the bread and add richness and structure.
Milk
Forms the liquid base of the custard and keeps the bread moist.
Bread
Soaks up the custard, then browns and crisps in the pan.
Sugar
Adds sweetness and helps the surface brown in the pan.

The step that matters

Frying each slice until golden brown. Frying over medium heat browns the sugars and proteins on the surface while the custard inside sets. Too high a heat scorches the outside before the center is cooked through.

Swap the lime

The recipe marks lime as optional. How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla, bread, ghee):

  1. Figfits better
  2. Coconutfits better
  3. Bananafits better
  4. Limethe original

Fit is the average pairing score against milk, egg, sugar, vanilla, bread, ghee. Candidates are from the same food group and used in at least 100 recipes.
