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, giving the water its toasty flavor and aroma.
- Boiling water
- Hot water draws the toasted flavors out of the bread into the liquid.
The step that matters
Toast the bread until uniformly brown, without scorching. Browning through Maillard reactions and caramelization builds the toasty flavor. Scorched areas turn bitter and burnt, and that taste carries into the water.
