Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee
- Provides the main flavour; boiling extracts it into the water.
- Boiling water
- Extracts the coffee's flavour and heats the pot before brewing.
- Thick sweet cream
- Adds richness and softens the bitterness of the coffee.
- Boiled milk
- Adds creaminess and mellows the coffee's sharp edges.
The step that matters
Keeping the coffee just below a boil after brewing. Once the coffee has boiled for 20 minutes, further boiling makes it increasingly bitter and can drive off aroma. Holding it hot without boiling keeps the flavour smoother until serving.
