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

What each ingredient does

Young walnuts
Provide the main flavour and colour as they steep in the brandy.
Brandy
Extracts flavour from the walnuts and acts as the base liquor that preserves the infusion.
Sugar
Adds sweetness to balance the bitter, astringent flavour of the walnuts.

The step that matters

Choosing young walnuts. Young walnuts have soft shells and tender interiors that release flavour into the brandy. Mature walnuts have hard, woody shells that resist infusion, so a pin test confirms the nuts are young enough to use.
