What each ingredient does
- Blackberries
- Provide the main fruit flavour, colour and juice for the cordial.
- Sugar
- Adds sweetness that balances the berries' tartness and helps preserve the liquid.
- Brandy
- Adds alcohol that helps preserve the cordial and carries its aroma.
The step that matters
Add the brandy only after the juice has cooled. Alcohol evaporates at a lower temperature than water, so brandy added to hot juice loses much of its alcohol and aroma. Cooling first keeps the spirit's strength and fragrance in the finished cordial.
