Why it works: Blackberry and whisky work together. They rank in the top 11% of all ingredient pairs, and cooks put them together in 25 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Blackberry juice
- Provides the main fruit flavour and colour, and forms the liquid base of the cordial.
- Sugar
- Adds sweetness and body, balancing the tartness of the blackberry juice.
- Whisky
- Adds alcohol that helps preserve the cordial and carries aroma and flavour.
The step that matters
Let the mixture cool before adding the whisky. Alcohol evaporates readily when heated, so adding whisky to a hot mixture would lose much of its alcohol and delicate aroma. Cooling first keeps the spirit's character in the finished cordial.

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