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

What each ingredient does

Stale bread
Toasting browns the bread, adding roasted, toasty flavor to the drink.
Boiling water
Hot water draws flavor and color out of the toasted bread as it steeps.
Cream
Adds fat for richer flavor and a smoother, softer mouthfeel.

The step that matters

Toast the bread until quite brown. Browning comes from Maillard reactions and caramelization, which build the roasted flavor this drink depends on. Underdone bread tastes flat, while over-darkened bread turns bitter and burnt.

Swap the lime

How well each one fits the dish's main ingredients (bread, cream):

  1. Raspberryfits better
  2. Vanillafits better
  3. Strawberryfits better
  4. Limethe original

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