Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee
- Provides the main roasted flavour and aroma, which are extracted into the hot water.
- Butter
- Adds fat that carries flavour and gives the roasted berries a richer, smoother character.
- Sugar
- Adds sweetness and promotes browning during roasting, helping develop deeper colour and flavour.
- Chicory
- Adds earthy, bitter notes and some body to the coffee blend.
- Boiling water
- Acts as the solvent that extracts soluble flavour compounds from the ground coffee.
- Milk
- Adds creaminess and softens the coffee's bitterness.
The step that matters
Roasting the berries with butter and sugar. Sugar browns and can scorch quickly at roasting temperatures, while the butter helps spread heat and coat the beans. Stirring constantly keeps the roast even and prevents bitter, burnt flavours.
