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

What each ingredient does

Arrowroot
Thickens the water into a clear, smooth broth as it heats.
Sherry or brandy
Adds aroma and a warm, fruity flavour at the end.
Sugar
Adds sweetness to balance the lemon and the alcohol.

The step that matters

Pour the boiling water over the moistened arrowroot. Arrowroot is a starch that must be fully hydrated and heated to thicken. Adding the hot water to a smooth slurry prevents lumps, and the mixture must return to the saucepan and boil so the starch can gel properly.
