Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Isinglass
Sets the liquid into a firm, clear jelly as it cools.
Fine clarified sugar syrup
Provides sweetness and body that balance the brandy and rose flavour.
Brandy
Adds aroma and warmth while keeping the jelly stable and flavourful.
Essence of roses
Gives the jelly its characteristic floral aroma.

The step that matters

Strain the mixture through a silk sieve. Straining removes impurities and undissolved particles, so the finished jelly sets clear and bright rather than cloudy.
