Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Toasted bread gives the water its browned, toasty flavor and color.
- Lemon
- Adds acidity and a bright citrus aroma to the water.
- Dried orange peel
- Its aromatic oils add a fragrant citrus note.
- Currant jelly
- Adds sweetness and a fruity flavor.
- Apples
- Add mild sweetness and a fruity body to the infusion.
The step that matters
Toast the bread until completely browned, but not burnt. Browning develops the toasty, roasted flavors that define the drink. Under-toasted bread tastes flat, while burnt bread adds bitter, acrid notes that spoil the water.
Swap the currant
How well each one fits the dish's main ingredients (bread, lemon, orange, apple):
- Cranberryfits better
- Figfits better
